Engineering Forestry Services

With forestry plantations exceeding 1.7 million hectares here in New Zealand, the need for increased safety and production in the forest and the supply chain is paramount in ensuring the ongoing growth and sustainability of the industry.

We work alongside you, using the latest CAD technologies and our extensive industry experience, to design and manufacture products we can all be proud of.

When it comes to your staff and equipment, compromise is not an option. Choose Trinder for forestry packages that go above and beyond to keep what matters most secure.


Working in the forest can be unpredictable, but ensuring your machine operators are protected from falling objects shouldn’t be. The Trinder Cab and Guarding packages enables you to choose the level of protection that suits your needs, from our solid base model to our ultimate premium package.

Every Trinder design considers weight, structural integrity and visibility without compromising operator comfort – because we know what’s at stake in the forestry industry. We’re not just about solutions; we’re about smart tested solutions. That’s why we collaborated with the University of Canterbury to engineer Cab designs that set industry benchmarks. We strive for nothing less than offering the best protection in the business.
