Engineering partners for New Zealand’s most demanding operations

Behind every reliable automation system is a team that understands what’s at stake.

From Hamilton to Southland, Nemesys engineers work alongside manufacturers to design, integrate, and support control systems that keep production moving, protect people, and stand up in real-world operating conditions.

We bring deep technical capability across industrial automation, control systems, and systems integration, backed by practical, on-site experience. That means fewer surprises, faster issue resolution, and solutions that continue to perform long after commissioning.

For engineers, this means working on complex, meaningful projects, alongside people who care about doing the job properly, not just getting it done.

Solutions Across Industries

We work in environments where reliability, safety, and performance are non-negotiable. Our industry experience means we understand the operational pressures, regulatory requirements, and real-world constraints unique to each sector.

Partnering for Performance in Critical Environments

We work alongside some of New Zealand’s most demanding operators to deliver automation and control systems that increase capacity, improve reliability, and perform under real-world pressure. As featured in Engineering New Zealand and CSL.

Nemesys partnered with the Te Rapa site to design and deliver automation and HMI integration for new chiller, filler, and FOSS systems.

The result was a boost from 30,000 to 33,500 tonne per year capacity lift, enabling both 5kg and 20kg product formats while maintaining strict quality and process control requirements.

Customer testimonials

“Detail-focused, and easy to work with.”

“Nemesys were proactive from the outset and highly detail-focused throughout delivery. Their simulation-first approach meant minimal on-site troubleshooting and a smooth transition into full production. The system performed as expected from day one.”
Karl Jamieson
Advanced Process Control Engineer

“This has been one of our biggest success stories this year.”

"The Nemesys team has done an outstanding job.

Our operators are now more confident with the automation, and the SCADA system has provided greater control, enabling faster problem-solving and improved production performance.

Through close collaboration, we’ve achieved a real steep change in team productivity, increasing production volumes substantially, all managed seamlessly with the same team.

This has been one of our biggest success stories this year."
Rob Buchan
Raglan Foods, Head of Technical Operations

“James & Sean were invaluable in our plants recent automation upgrades”

"Their willingness to being proactive and assist the plant helped the project along which resulted in a successful project. Was refreshing having people who were committed & knowledgeable working on the project and were willing to be flexible to cater to the production requirements.

Would like to thank James & Sean for all their hard work making the project successful."

“We felt you could do the job — and so far, you’ve backed that up.”

“Price was a key factor in our decision, but equally important was our confidence in your technical capabilities and the strength of our working relationship.

We felt you could do the job — and so far, you’ve backed that up. There haven’t been any real hesitations or issues since we started.

The only thing that could have held us back was if we’d found any gaps in your technical knowledge — and that hasn’t been the case. Everything has been going smoothly.”
Mark Taylor
Senior Manager Electrical & Automation GEA

“Met our performance targets.”

We chose to work with you because of your strong familiarity with our site and the confidence your team inspires in our maintenance staff. One of the biggest factors was knowing that support would always be available when we needed it — and you’ve proven that time and again.

What really sets you apart is your willingness to jump in and help immediately, even before commercial details are finalised. Unlike others who delay support until paperwork is in place, your responsiveness has made a real difference.

While other projects may have hesitated due to the lack of a working demonstration, for us personally, there were no barriers — and we’re glad we made the decision.
