Design, Research & Development
When you want to take your engineering research and innovative solutions to the cutting edge, talk to us about our integrated research and innovation (R&I) services. Trinder have a proven and enviable history when it comes to developing world class products and equipment.
Smarter engineering. Better outcomes.
At Trinder, our professional engineers have extensive design, innovation, and development experience to transform your design specification and concept ideas into CAD models, technical drawings, and manufactured design solutions.
With decades of experience, our team understands what it takes to design solutions that not only work on paper — but deliver reliable results in the real world, under real world operating conditions.
Our Engineering Design services
Trinder offers a full range of engineering design capabilities to meet the demands of a wide range of industries — from heavy industrial plant and machinery, to structural building fabrication, through to materials handling and agriculture.
Concept Development & Feasibility Studies
Before a project begins, Trinder will ensure the concept is economically viable, practically achievable, and aligned with your objectives. We assess risk, regulatory requirements, and design constraints early, avoiding costly redesigns.
Detailed Design & Construction Documentation
Our engineers deliver complete, accurate, and compliant design packages — including concept and fabrication drawings and calculations. We use industry-leading CAD and analysis tools to model, validate, and refine the concept to the final design solution.
Mechanical & Structural Engineering
We have the capability to design everything from structural steel to mechanical systems, with an emphasis on safety, durability, and performance. This includes industrial platforms, conveyors, walkways, machine safety and equipment housings, and pressure-rated components.
Design for Manufacture & Assembly (DfMA)
Our team ensures every design is optimised for real-world fabrication and installation — reducing errors, saving time, and improving efficiency on site.
Compliance & Regulatory Guidance
Navigating New Zealand’s compliance environment can be complex – our experience will simplify the requirements. From compliance with applicable standards to Worksafe NZ regulations, we design with compliance in mind.


Our process: designed for delivery
Every project follows a structured, stage-gated process — designed to reduce risk, ensure clarity, and deliver outcomes that exceed expectations. Project invoicing is aligned with each stage with progress claims issued with each deliverable.
Experience you can build on
Clients across New Zealand trust Trinder for one key reason: we understand what makes engineering design successful — in the field, not just in theory.
Multidisciplinary expertise
We combine professional mechanical engineers with qualified fabrication staff into a seamless offering — no need to juggle multiple businesses, consultants or engineers.
Proven track record
From facility upgrades to industrial machinery installations, we’ve delivered successful outcomes for councils, contractors, and private clients across the country.
Buildable, practical designs
Our designs are informed by decades of hands-on fabrication and project delivery experience. That means fewer surprises, faster installs, and reduced costs.
Part of a full-service engineering company
As part of the wider Trinder group, we offer true design-to-delivery capability — including fabrication, installation, and ongoing support.
Sustainable by design
Engineering has a key role to play in building a more sustainable future — and at Trinder, we take that responsibility seriously.
From material selection and lifecycle considerations to energy efficiency and emissions reduction, our team embeds sustainable principles into every phase of the design process.
Real projects. Measurable impact.
