The power of gender parity in engineering
OPINION by Dr Troy Coyle, HERA CEO
As we celebrate Women’s Suffrage Day on 19 September 2024, it’s an opportunity to reflect on the critical role women play in shaping the future of engineering and construction.
This is a topic I’m very passionate about, and I’m honoured to be a panellist at the National Association of Women in Construction (NAWIC) event, celebrating wāhine who are driving change in our industry on this very day.
While we’re making strides, much more work remains to be done.
Diversity drives innovation
At HERA, we’ve always known that diverse teams lead to better outcomes. Diversity isn’t just a box to tick—it’s essential to fostering innovation and achieving success in a rapidly evolving industry. Within our Endeavour Fund supported Construction 4.0, project we’re seeing how diverse perspectives can drive new approaches and lead to more creative problem-solving.
It is why we are so proud to have recently achieved a significant milestone in our Structural Systems team—gender parity. This wasn’t a goal we set out to achieve explicitly, but by making a few key changes in how we recruit, we’ve proven that gender balance is not only possible, it’s powerful. Our introduction of flexible work environments, whānau-friendly leave options, inclusive job advertisements and a focus on potential has seen more female candidates apply for our roles.
The result has been gender parity in our leadership team, more wāhine on our board and now in our wider team.
Reaching those who aren’t listening
While we celebrate these wins, there’s a greater challenge ahead. Too often, those attending diversity-focused events already understand the importance of inclusion. Every time we lead conversations in this space, I notice that engagement is always low compared to other content we share. How do we reach those who aren’t in the room?
The reality is, the people who most need to hear the message of inclusion are often the ones not engaging in these conversations. Real progress requires us to go beyond the events and panels and embed diversity into every facet of our industry. It’s not enough to celebrate in our own echo chambers. We must actively engage those who resist change and demonstrate that fostering diversity isn’t just the right thing to do—it makes business sense.
Action, not just conversation
At HERA, we’re continuously working to create an inclusive environment where women, particularly wāhine Māori, can thrive. We’re proud of our diverse team, representing countries and cultures from New Zealand, Fiji, Iran, Ukraine, Turkey, India, Australia, Germany, Hungary, Serbia, and France.
But this isn’t the finish line. The future of engineering and construction depends on broadening the conversation and proving the tangible benefits of diversity. The more inclusive we are, the stronger and more innovative our industry becomes. If you are reading this in time – please register to attend the ‘We Belong’ event. I look forward to seeing you there. Event registration: https://events.humanitix.com/auckland-we-belong-women-pioneering-the-future-in-construction
It’s time to reset the New Zealand approach to health and safety
OPINION By Craig Carlyle, certified machinery safety expert (TÜV Nord)
Do we need another reset in our approach to improving our health and safety? If you look at our hellish traffic management approach, as a perfect example, it is a resounding ‘yes’. And WorkSafe have got something to do with it.
Road traffic safety is the high-profile example of the lunacy, with a whole new industry where previously none existed; stop go, road cones, full road closures, unending delays and frustrations for the public, and comedic approaches to weeding roundabouts. All in the name of health and safety. So, are we killing and injuring any less road workers? Nope, about the same as previous decades. Are we paying through the nose for these extra resources and delays? Yes.
So how did we end up in this mess? We can trace it back to WorkSafe’s penchant for prosecuting the PCBU’s and directors. WorkSafe are the inspectorate, so like the police, their job is to apply the laws and regulations. Rightly or wrongly, they have zealously pursued the top of the food chain, convinced that this will force change. It certainly has. But not the right kind of change. In fact, it is a spectacular failure.
Refer traffic management. Pressure from the top down after several high-profile road work fatality prosecutions has cascaded down to the illogical and over the top results we observe daily. Instead of upwardly driven logic, we are back to cover your arse, tick the box clerical safety and health and safety fashion. The costs are accepted and passed up the chain, (eventually to us), by the players, who are clipping the ticket along the way and not about to bite the hand feeding them. While it is un-PC to deny the safety card, (how dare you!), the public can clearly see the emperor is wearing fluro clothes.
Road construction is not unique, but it is a high-profile example of where we are going wrong. If all this cost and constraint since 1992 was even slightly effective, we should be experiencing a paradigm shift in our statistics. But we are not. All we have learnt is what does not work. Returning to WorkSafe, they need to think about two core approaches, who they are focusing on and the balance between the carrot and stick.
The recent prosecution of a worker (a fishing charter Captain) was so rare it deserves mention. Workers have distinct duties under the laws and regulations, but they seldom feature in prosecutions. More focus on workers may help drive the message that we are responsible for ourselves and our mates, as opposed to safety being a management ‘thing’. When was the last time a WorkSafe investigation focused on the victim’s peers and their actions or inactions? We are living the result of aiming at the top of the totem pole.
Business’s feel trapped by the current regime. In 2015, WorkSafe were charged with providing both carrot and stick and did a pretty good job of making information available on their website. But while WorkSafe are very good at telling business’s what they have done wrong after an event, business’s ability to tap into the same advice and opinion proactively is problematic. The WorkSafe line is that they are “not here to consult”. Meanwhile, the current approach of a WorkSafe inspector knocking at the door and then leaving a stack of punitive improvement notices behind does not induce confidence and trust from industry.
Yes, we can do better. But we need to change something first. The first step is to recognise what we are doing is not working.
On the right road…
Empowering RTL to streamline and improve operations
RTL designs and manufactures a substantial percentage of New Zealand’s road signs nationally and RTL employs a total of 45 staff and management and operates across 4,000 square metres of factory and office space located in Auckland, Wellington, Christchurch, and Invercargill.
RTL utilises Empower, a labour management software, to gauge the productivity of its labour force. To streamline its operations, RTL enlisted the services of Xenia Suite to create an interface between MYOB GreenTree and Empower.
The interface developed by Xenia Suite facilitates the automatic transfer of new orders from GreenTree to Empower. This integration eliminates the need for redundant data entry, effectively merging GreenTree and Empower into a cohesive and efficient software solution. The interface ensures a seamless and integrated experience, consolidating GreenTree and Empower into what the supply company describes as a unified “world class” software solution.
Also, the automatic data transfer minimises the need for double data entry, enhancing operational efficiency. The successful development of the interface between MYOB GreenTree and Empower by Xenia Suite has significantly improved RTL’s labour recovery, fostering a more streamlined and efficient labour management process.
“Through the utilisation of Empower, we effectively manage our daily, weekly, and monthly workload by assigning tasks and jobs to our workshop staff while monitoring actual versus budgeted times at both the job and task levels for each staff member,” says Kourosh Darvish, production manager at RTL.
Darvish says that this specialised software, designed for manufacturers, plays a “pivotal role in tracking and reporting jobs and tasks down to the necessary task level, as well as tracking and reporting times down to the crucial individual workshop staff level.”
Empower software has significantly enhanced RTL’s performance, as evidenced by the following Key Performance Indicators:
• A notable reduction of approximately 20% in time on jobs.
• A 50% decrease in downtime and unaccounted time.
• An 80 to 90% reduction in the significant time slippage around promptness at the start of the day, break times, and lunch times at the end of the day. These improvements have collectively led to substantial time savings, resulting in a positive impact on our daily production and overall profitability.

Stay in the black with corrosion inhibiting bearings
Soil ingress on equipment in agricultural applications can create significant problems for farmers in terms of machine performance and longevity. Bearings in particular are susceptible to failure from exposure to harsh environmental operating conditions – and when every minute of uptime counts, it’s important to choose the right bearings for the job, says Nick Hems, Motion’s category manager for bearings.
“Soil, dust and water ingression is an ongoing threat to equipment, particularly in New Zealand where farmers contend with extreme weather conditions – from hot and cold to dust and heavy rain,” says Hems. “This is why investing in bearings built to withstand the harshest of conditions is critical, particularly when there is huge demand for food product. No one wants to experience downtime especially during harvest season.”
Hems explains that the latest iteration of the Schaeffler FAG Black Series have features specifically built for harsh agricultural applications.
“The FAG Black Series of radial insert ball bearings and housing units from Schaeffler are robust, ready-to fit, self-contained units that provide simplified mounting, smooth running and high reliability. These bearings and housing units have superior sealing and corrosion protection. This is especially important as rust leads to flaking and premature failure. And bearing failure is one of the most common – and preventable – causes of farming equipment breakdowns.”
The Black Series take its name from their matte black surface coating. The black coating is Schaeffler’s Durotect BS surface treatment formulated to inhibit rust on external surfaces and to reduce fretting corrosion between bearing and shaft.
“These bearings will still perform well despite harsh conditions – they are durable and reliable.” The Black Series housing units consist of high strength graphite cast iron precisely machined to provide a tight J7 fit with the self-aligning bearing insert.
“They’re particularly suitable for applications with light to medium radial loads. The housing units also allow for relubrication to increase longevity of the bearings and prevent build-up of dust, sludge and static contaminants that can slow down equipment,” says Hems
The Black Series radial insert ball bearings are available with three shaft locking options being grub screw lock, eccentric collar lock and tapered adapter sleeve lock. Housing configurations include several options of pillow block and flanged types plus a take up housing option.
The insert bearings are based on single row deep groove ball bearings and comprise a solid section outer ring and an inner
ring extended on both sides. The bearings have low friction plastic cages and are sealed on both sides by single piece seals with a vulcanised lip and outer flinger shield.
“Because of the way they are designed, they have reduced frictional torque, so they are more energy efficient and generate less heat which also extends grease life,” Hems says.
“Importantly, the ball bearings and housing units are particularly easy to install. Housing units are supplied with a lubrication nipple with integrated seal cap as well as an Allen key for bearings with grub screw lock.”
Hems recommends that customers call on Motion before changing over or installing bearings because a local Motion branch can draw on the nationwide expertise of engineers and experts and provide highly localised service and support.
“If customers are having difficulties with their equipment and bearings, we’re here to help. Whether that’s about supplying the right bearing to their application, or questions about installation and best practices, we’re available around the clock.”

Mettler-Toledo
Supporting local engineers to produce safe, quality food production machinery
Engineering in the food industry is a dynamic and ever-evolving sector characterised by stringent quality standards, regulatory compliance, and the constant need for innovation to meet consumer demands.
According to Alni Tatari, Mettler-Toledo business area manager, companies in this industry must navigate complex formulation processes, manage diverse ingredient lists, and ensure consistent product quality while minimising waste and costs,
“Mettler-Toledo understands the importance of quality, safety and efficiency in this sector and is committed to helping engineers in the food industry produce safe, high-quality products that meet consumer expectations and regulatory standards,” says Tatari.
Form+ is an advanced formulation software that automates intricate calculations, ensuring precise ingredient measurements and adherence to regulatory requirements.
“These capabilities streamline the formulation process and enhance product consistency and quality within clearly defined process tolerances. Form+ facilitates innovation by allowing easy adjustments and scenario testing, enabling rapid development of new products. Its user-friendly interface and robust data management capabilities integrate seamlessly into existing workflows, driving efficiency, reducing formulation time, and ultimately delivering significant cost savings.
“By leveraging Form+, food and beverage manufacturers can achieve greater productivity, maintain high standards, and stay competitive in a challenging market.”
Tatari says that paper-based formulation systems are prone to errors due to simple human mistakes and unreadable handwriting. Operators must focus on producing high-quality products while also documenting the production results. In the case of a bad batch or recall, these documents must be sorted and reviewed manually, which is extremely time-consuming and does not provide full process visibility to prevent the error the next time.
“With Form+, operators can confidently work in your data as it ensures reliable, traceable data and improved productivity so they can focus on production without being distracted by manual documentation requirements.
“Another benefit of Form+ is operators can remotely manage data through automatic documentation, which ensures that operators have data to verify your process and the ability to monitor from anywhere within the facility. Avoid documentation of incorrect data, lost papers, scribbled handwriting, and data-entry errors – forever. You can access the data you need as soon as possible,” says Tatari.
Not only does this improve user experience, explains Tatari, but it offers systematic improvement without complexity for operators. It facilitates easy recipe and production management and step-by-step guidance for operators. This user-friendly setup allows operators to gain efficiencies in their repetitive processes without increasing the risk of errors.
“Form+ gives operators the flexibility to work how they want through its intelligent recipe development by having the capabilities to seamlessly integrate into companies’ existing production processes and IT environment. Operations achieve major quality improvements with little effort for installation and scale-up,” says Tatari.
“Mettler-Toledo understands the importance of quality, safety and efficiency in this sector and will continue to leverage our expertise in helping businesses automate their weighing processes and are committed to providing our customers with the best practical solutions and guidance so that the food industry can focus on what they do best – producing high-quality products.”

The lights are powered by the blowing unit, and they automatically turn off or on based on the ambient light. Alternatively, they can be easily controlled manually by hand.
Users can choose from six helmet models within the range.
Directors must lead health and safety improvements
New Zealand directors must actively play their part to improve health and safety outcomes in New Zealand, say Institute of Directors (IoD) GM Governance Leadership Centre Guy Beatson and WorkSafe New Zealand chair Jennifer Kerr.
The IoD and WorkSafe recently released a new resource – Health and Safety: A good practice guide – to help directors and other officers, as they are known under legislation, find ways to improve their own organisations’ performance.
“Research by the Business Leaders’ Health and Safety Forum shows our health and safety performance continues to flatline, when compared to Australia and the UK,” says Beatson.
“A survey by the Forum in March found 90% of business leaders feel the government should prioritise improving our health and safety performance, and there was a general sentiment that guidance and regulation around health and safety should be clarified and simplified.”
Produced in association with the Business Leaders Health and Safety Forum, the general manager Safety Forum, and WorkSafe, the revised guide outlines a principles-based approach and a focus on understanding and managing risk.
“While the ultimate goal is to reduce workplace fatalities and injuries, a governance approach that focuses on statistics will not necessarily achieve that outcome,” Beatson says.
“We advocate that boards take a lead by looking beyond the statistics to understand the entire health and safety ecosystem. For example, do they get reports on risks that have not, fortunately, led to an incident yet? They should also seek to understand the perspectives of their workers and incorporate these into board thinking, alongside the advice of industry experts.
“Courageous and honest conversations around the board table have the potential to improve our health and safety record more than further tinkering with regulations at a government level,” he says.
“WorkSafe, Aotearoa New Zealand’s primary work health and safety regulator, is pleased to support this revised guide which was developed by industry for industry,” says Jennifer Kerr.
“It is great to see businesses taking a lead and supporting those in roles like mine with resources on what good governance looks like in relation to work health and safety.
“This guide offers invaluable advice and practical guidance on how those in governance roles can contribute to better work health and safety outcomes,” says Kerr.
‘Health and Safey: A good practice guide’ is a new version of what was known as “the Blue Book”. It is available for download at iod.org.nz.
Ara Timaru new trades building provides more learning space
The tapu on Ara Institute of Canterbury’s new trades building in Timaru, which has been completed on time and on budget, has been lifted.
The building’s name, Tūterakiwhanoa, has been gifted by Te Runanga o Arowhenua and represents the Kai Tahu ancestor who, according to pūrākau (Māori creation stories) brought habitation to Te Waipounamu (the South Island).
Representatives from manawhenua, led by Te Rūnanga o Arowhenua upoko (head) Te Wera King, officially bless the $2.5 million building, offering a karakia whakatuwhera to signify the commencement of something new.
The rūnganga performed a key role ahead of the build, instilling mauri (life force) into a special kohatu (stone) which has been embedded in the building’s foundation. A kowhai tree, which was blessed in acknowledgement of the physical resource being invested into the project will be planted at the tapu-lifting ceremony if ground conditions permit.
The ceremony marks the transition from building site to new build – ready for fit out and the arrival of ākonga (students) in the weeks ahead. A formal opening will be held once it’s fully operational.
At approximately 780m2, Tūterakiwhanoa replaces current facilities dating back to the 1960s. It will provide a mix of engineering spaces for activities for multiple learning streams, including gas and electric welding, lathe and machining and fabrication.
It will allow Ara to expand its training options, provide improved space for learning and the flexibility to replace and change equipment in the future to meet the changing needs of industry.
“It’s a move to a more contemporary learning environment, reflective of the expectation of a modern educational facility and mimicking what can be found in the workplace,” says regional executive director and Ara business division lead Darren Mitchell.
“It will allow for larger class sizes to suit forecast growth with better work zones and will ultimately lead to a far better learning experience for students,” Mitchell adds.
The design and build has been led by Colin Shore Builders who, having been involved since very early in the process, are credited with saving the project time and money. The project has utilised local contractors where possible including local architect John Rushton.
Mitchell says the project builds on the district’s strong history in the engineering, welding and fabrication fields, based around the rural sector and the port.
The power of gender parity in engineering
OPINION by Dr Troy Coyle, HERA CEO
As we celebrate Women’s Suffrage Day on 19 September 2024, it’s an opportunity to reflect on the critical role women play in shaping the future of engineering and construction.
This is a topic I’m very passionate about, and I’m honoured to be a panellist at the National Association of Women in Construction (NAWIC) event, celebrating wāhine who are driving change in our industry on this very day.
While we’re making strides, much more work remains to be done.
Diversity drives innovation
At HERA, we’ve always known that diverse teams lead to better outcomes. Diversity isn’t just a box to tick—it’s essential to fostering innovation and achieving success in a rapidly evolving industry. Within our Endeavour Fund supported Construction 4.0, project we’re seeing how diverse perspectives can drive new approaches and lead to more creative problem-solving.
It is why we are so proud to have recently achieved a significant milestone in our Structural Systems team—gender parity. This wasn’t a goal we set out to achieve explicitly, but by making a few key changes in how we recruit, we’ve proven that gender balance is not only possible, it’s powerful. Our introduction of flexible work environments, whānau-friendly leave options, inclusive job advertisements and a focus on potential has seen more female candidates apply for our roles.
The result has been gender parity in our leadership team, more wāhine on our board and now in our wider team.
Reaching those who aren’t listening
While we celebrate these wins, there’s a greater challenge ahead. Too often, those attending diversity-focused events already understand the importance of inclusion. Every time we lead conversations in this space, I notice that engagement is always low compared to other content we share. How do we reach those who aren’t in the room?
The reality is, the people who most need to hear the message of inclusion are often the ones not engaging in these conversations. Real progress requires us to go beyond the events and panels and embed diversity into every facet of our industry. It’s not enough to celebrate in our own echo chambers. We must actively engage those who resist change and demonstrate that fostering diversity isn’t just the right thing to do—it makes business sense.
Action, not just conversation
At HERA, we’re continuously working to create an inclusive environment where women, particularly wāhine Māori, can thrive. We’re proud of our diverse team, representing countries and cultures from New Zealand, Fiji, Iran, Ukraine, Turkey, India, Australia, Germany, Hungary, Serbia, and France.
But this isn’t the finish line. The future of engineering and construction depends on broadening the conversation and proving the tangible benefits of diversity. The more inclusive we are, the stronger and more innovative our industry becomes. If you are reading this in time – please register to attend the ‘We Belong’ event.

It’s time to reset the New Zealand approach to health and safety
OPINION By Craig Carlyle, certified machinery safety expert (TÜV Nord)
Do we need another reset in our approach to improving our health and safety? If you look at our hellish traffic management approach, as a perfect example, it is a resounding ‘yes’. And WorkSafe have got something to do with it.

Business’s feel trapped by the current regime. In 2015, WorkSafe were charged with providing both carrot and stick and did a pretty good job of making information available on their website. But while WorkSafe are very good at telling business’s what they have done wrong after an event, business’s ability to tap into the same advice and opinion proactively is problematic. The WorkSafe line is that they are “not here to consult”. Meanwhile, the current approach of a WorkSafe inspector knocking at the door and then leaving a stack of punitive improvement notices behind does not induce confidence and trust from industry.
Yes, we can do better. But we need to change something first. The first step is to recognise what we are doing is not working.
On the right road…
Empowering RTL to streamline and improve operations
RTL designs and manufactures a substantial percentage of New Zealand’s road signs nationally and RTL employs a total of 45 staff and management and operates across 4,000 square metres of factory and office space located in Auckland, Wellington, Christchurch, and Invercargill.
RTL utilises Empower, a labour management software, to gauge the productivity of its labour force. To streamline its operations, RTL enlisted the services of Xenia Suite to create an interface between MYOB GreenTree and Empower.
The interface developed by Xenia Suite facilitates the automatic transfer of new orders from GreenTree to Empower. This integration eliminates the need for redundant data entry, effectively merging GreenTree and Empower into a cohesive and efficient software solution. The interface ensures a seamless and integrated experience, consolidating GreenTree and Empower into what the supply company describes as a unified “world class” software solution.
Also, the automatic data transfer minimises the need for double data entry, enhancing operational efficiency. The successful development of the interface between MYOB GreenTree and Empower by Xenia Suite has significantly improved RTL’s labour recovery, fostering a more streamlined and efficient labour management process.
“Through the utilisation of Empower, we effectively manage our daily, weekly, and monthly workload by assigning tasks and jobs to our workshop staff while monitoring actual versus budgeted times at both the job and task levels for each staff member,” says Kourosh Darvish, production manager at RTL.
Darvish says that this specialised software, designed for manufacturers, plays a “pivotal role in tracking and reporting jobs and tasks down to the necessary task level, as well as tracking and reporting times down to the crucial individual workshop staff level.”
Empower software has significantly enhanced RTL’s performance, as evidenced by the following Key Performance Indicators:
• A notable reduction of approximately 20% in time on jobs.
• A 50% decrease in downtime and unaccounted time.
• An 80 to 90% reduction in the significant time slippage around promptness at the start of the day, break times, and lunch times at the end of the day. These improvements have collectively led to substantial time savings, resulting in a positive impact on our daily production and overall profitability.

Stay in the black with corrosion inhibiting bearings
Soil ingress on equipment in agricultural applications can create significant problems for farmers in terms of machine performance and longevity. Bearings in particular are susceptible to failure from exposure to harsh environmental operating conditions – and when every minute of uptime counts, it’s important to choose the right bearings for the job, says Nick Hems, Motion’s category manager for bearings.
“Soil, dust and water ingression is an ongoing threat to equipment, particularly in New Zealand where farmers contend with extreme weather conditions – from hot and cold to dust and heavy rain,” says Hems. “This is why investing in bearings built to withstand the harshest of conditions is critical, particularly when there is huge demand for food product. No one wants to experience downtime especially during harvest season.”
Hems explains that the latest iteration of the Schaeffler FAG Black Series have features specifically built for harsh agricultural applications.
“The FAG Black Series of radial insert ball bearings and housing units from Schaeffler are robust, ready-to fit, self-contained units that provide simplified mounting, smooth running and high reliability. These bearings and housing units have superior sealing and corrosion protection. This is especially important as rust leads to flaking and premature failure. And bearing failure is one of the most common – and preventable – causes of farming equipment breakdowns.”
The Black Series take its name from their matte black surface coating. The black coating is Schaeffler’s Durotect BS surface treatment formulated to inhibit rust on external surfaces and to reduce fretting corrosion between bearing and shaft.
“These bearings will still perform well despite harsh conditions – they are durable and reliable.” The Black Series housing units consist of high strength graphite cast iron precisely machined to provide a tight J7 fit with the self-aligning bearing insert.
“They’re particularly suitable for applications with light to medium radial loads. The housing units also allow for relubrication to increase longevity of the bearings and prevent build-up of dust, sludge and static contaminants that can slow down equipment,” says Hems
The Black Series radial insert ball bearings are available with three shaft locking options being grub screw lock, eccentric collar lock and tapered adapter sleeve lock. Housing configurations include several options of pillow block and flanged types plus a take up housing option.
The insert bearings are based on single row deep groove ball bearings and comprise a solid section outer ring and an inner
ring extended on both sides. The bearings have low friction plastic cages and are sealed on both sides by single piece seals with a vulcanised lip and outer flinger shield.
“Because of the way they are designed, they have reduced frictional torque, so they are more energy efficient and generate less heat which also extends grease life,” Hems says.
“Importantly, the ball bearings and housing units are particularly easy to install. Housing units are supplied with a lubrication nipple with integrated seal cap as well as an Allen key for bearings with grub screw lock.”
Hems recommends that customers call on Motion before changing over or installing bearings because a local Motion branch can draw on the nationwide expertise of engineers and experts and provide highly localised service and support.
“If customers are having difficulties with their equipment and bearings, we’re here to help. Whether that’s about supplying the right bearing to their application, or questions about installation and best practices, we’re available around the clock.”

Mettler-Toledo
Supporting local engineers to produce safe, quality food production machinery
Engineering in the food industry is a dynamic and ever-evolving sector characterised by stringent quality standards, regulatory compliance, and the constant need for innovation to meet consumer demands.
According to Alni Tatari, Mettler-Toledo business area manager, companies in this industry must navigate complex formulation processes, manage diverse ingredient lists, and ensure consistent product quality while minimising waste and costs,
“Mettler-Toledo understands the importance of quality, safety and efficiency in this sector and is committed to helping engineers in the food industry produce safe, high-quality products that meet consumer expectations and regulatory standards,” says Tatari.
Form+ is an advanced formulation software that automates intricate calculations, ensuring precise ingredient measurements and adherence to regulatory requirements.
“These capabilities streamline the formulation process and enhance product consistency and quality within clearly defined process tolerances. Form+ facilitates innovation by allowing easy adjustments and scenario testing, enabling rapid development of new products. Its user-friendly interface and robust data management capabilities integrate seamlessly into existing workflows, driving efficiency, reducing formulation time, and ultimately delivering significant cost savings.
“By leveraging Form+, food and beverage manufacturers can achieve greater productivity, maintain high standards, and stay competitive in a challenging market.”
Tatari says that paper-based formulation systems are prone to errors due to simple human mistakes and unreadable handwriting. Operators must focus on producing high-quality products while also documenting the production results. In the case of a bad batch or recall, these documents must be sorted and reviewed manually, which is extremely time-consuming and does not provide full process visibility to prevent the error the next time.
“With Form+, operators can confidently work in your data as it ensures reliable, traceable data and improved productivity so they can focus on production without being distracted by manual documentation requirements.
“Another benefit of Form+ is operators can remotely manage data through automatic documentation, which ensures that operators have data to verify your process and the ability to monitor from anywhere within the facility. Avoid documentation of incorrect data, lost papers, scribbled handwriting, and data-entry errors – forever. You can access the data you need as soon as possible,” says Tatari.
Not only does this improve user experience, explains Tatari, but it offers systematic improvement without complexity for operators. It facilitates easy recipe and production management and step-by-step guidance for operators. This user-friendly setup allows operators to gain efficiencies in their repetitive processes without increasing the risk of errors.
“Form+ gives operators the flexibility to work how they want through its intelligent recipe development by having the capabilities to seamlessly integrate into companies’ existing production processes and IT environment. Operations achieve major quality improvements with little effort for installation and scale-up,” says Tatari.
“Mettler-Toledo understands the importance of quality, safety and efficiency in this sector and will continue to leverage our expertise in helping businesses automate their weighing processes and are committed to providing our customers with the best practical solutions and guidance so that the food industry can focus on what they do best – producing high-quality products.”

Directors must lead health and safety improvements
New Zealand directors must actively play their part to improve health and safety outcomes in New Zealand, say Institute of Directors (IoD) GM Governance Leadership Centre Guy Beatson and WorkSafe New Zealand chair Jennifer Kerr.
The IoD and WorkSafe recently released a new resource – Health and Safety: A good practice guide – to help directors and other officers, as they are known under legislation, find ways to improve their own organisations’ performance.
“Research by the Business Leaders’ Health and Safety Forum shows our health and safety performance continues to flatline, when compared to Australia and the UK,” says Beatson.
“A survey by the Forum in March found 90% of business leaders feel the government should prioritise improving our health and safety performance, and there was a general sentiment that guidance and regulation around health and safety should be clarified and simplified.”
Produced in association with the Business Leaders Health and Safety Forum, the general manager Safety Forum, and WorkSafe, the revised guide outlines a principles-based approach and a focus on understanding and managing risk.
“While the ultimate goal is to reduce workplace fatalities and injuries, a governance approach that focuses on statistics will not necessarily achieve that outcome,” Beatson says.
“We advocate that boards take a lead by looking beyond the statistics to understand the entire health and safety ecosystem. For example, do they get reports on risks that have not, fortunately, led to an incident yet? They should also seek to understand the perspectives of their workers and incorporate these into board thinking, alongside the advice of industry experts.
“Courageous and honest conversations around the board table have the potential to improve our health and safety record more than further tinkering with regulations at a government level,” he says.
“WorkSafe, Aotearoa New Zealand’s primary work health and safety regulator, is pleased to support this revised guide which was developed by industry for industry,” says Jennifer Kerr.
“It is great to see businesses taking a lead and supporting those in roles like mine with resources on what good governance looks like in relation to work health and safety.
“This guide offers invaluable advice and practical guidance on how those in governance roles can contribute to better work health and safety outcomes,” says Kerr.
‘Health and Safey: A good practice guide’ is a new version of what was known as “the Blue Book”. It is available for download at iod.org.nz.
Ara Timaru new trades building provides more learning space
The tapu on Ara Institute of Canterbury’s new trades building in Timaru, which has been completed on time and on budget, has been lifted.
The building’s name, Tūterakiwhanoa, has been gifted by Te Runanga o Arowhenua and represents the Kai Tahu ancestor who, according to pūrākau (Māori creation stories) brought habitation to Te Waipounamu (the South Island).
Representatives from manawhenua, led by Te Rūnanga o Arowhenua upoko (head) Te Wera King, officially bless the $2.5 million building, offering a karakia whakatuwhera to signify the commencement of something new.
The rūnganga performed a key role ahead of the build, instilling mauri (life force) into a special kohatu (stone) which has been embedded in the building’s foundation. A kowhai tree, which was blessed in acknowledgement of the physical resource being invested into the project will be planted at the tapu-lifting ceremony if ground conditions permit.
The ceremony marks the transition from building site to new build – ready for fit out and the arrival of ākonga (students) in the weeks ahead. A formal opening will be held once it’s fully operational.
At approximately 780m2, Tūterakiwhanoa replaces current facilities dating back to the 1960s. It will provide a mix of engineering spaces for activities for multiple learning streams, including gas and electric welding, lathe and machining and fabrication.
It will allow Ara to expand its training options, provide improved space for learning and the flexibility to replace and change equipment in the future to meet the changing needs of industry.
“It’s a move to a more contemporary learning environment, reflective of the expectation of a modern educational facility and mimicking what can be found in the workplace,” says regional executive director and Ara business division lead Darren Mitchell.
“It will allow for larger class sizes to suit forecast growth with better work zones and will ultimately lead to a far better learning experience for students,” Mitchell adds.
The design and build has been led by Colin Shore Builders who, having been involved since very early in the process, are credited with saving the project time and money. The project has utilised local contractors where possible including local architect John Rushton.
Mitchell says the project builds on the district’s strong history in the engineering, welding and fabrication fields, based around the rural sector and the port.
