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.
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.
Automation that protects quality, throughput, and compliance. We help food and beverage manufacturers maintain consistent production, meet strict safety standards, and scale output without compromising quality or uptime.
Critical infrastructure that performs around the clock. From treatment plants to network assets, we deliver automation and control systems that support continuous operation, regulatory compliance, and long-term asset performance.

Engineered for safety, resilience, and long service life. We support complex energy and infrastructure projects with control systems designed to operate reliably in demanding, safety-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.
Automation of Open Country Dairy's entire AMF plant at Awarua, covering separation and concentration, stockfood loadout, and filling and drumming, integrated with existing site control systems.

At Nemesys, we don’t just deliver automation, we design systems that are easier to deploy, simpler to operate, and more reliable over their full lifecycle.
Our approach combines strong engineering fundamentals with modern development practices, helping organisations reduce delivery risk, shorten commissioning time, and operate with confidence long after handover.
Our insights share how we approach automation, safety, and system integration in real operating environments, translating technical decisions into measurable performance, reliability, and long-term value.
Whether you’re responsible for operations, engineering, or asset performance, these resources are designed to help you make better-informed decisions.
Discover how we use Manufacturing Execution Systems (MES) to turn real-time production data into clear operational insight, helping teams optimise processes, reduce waste, and improve overall plant efficiency and profitability.
Learn how Nemesys designs certified functional safety systems that protect people and equipment while supporting productivity, compliance, and long-term operational confidence.
See how targeted automation and system integration increased production by 3,500 tonnes per year, enabling new product streams and improved efficiency at the Fonterra Te Rapa site.
