Let us introduce you to our team, one by one...
This year, we expanded our team and welcomed Simon Jones as our Territory Manager for North/West Auckland and Northland. And because we now have two Simons, two Steves, and a Rich, we figured it was time to let them introduce themselves properly. Let’s start with Symon Maxwell, South/East Auckland and Northern Waikato Territory Manager…

Q&A
Q. What do you enjoy most about working with Trenchmate customers?
A. Telling the story of New Zealand-owned, South Auckland–made products and seeing customers’ reactions when they realise the level of Kiwi engineering that goes into them.

Q. One project you’re proud of?
A. My first Siltmate job – it was a retirement village in my home suburb. It was a great learning experience, and the client couldn’t believe how clean the discharged water was.

Q. Something people might be surprised to learn about Trenchmate?
A. As well as standard shields, we can also customise shoring solutions to fit any job – we’re not a cookie-cutter operation.

🚜 First job: I worked for a local earth-moving company.
💡 Best work philosophy: Always do what I say I will do.

Our Story

At Trenchmate, we’ve been designing, manufacturing and supplying superior shoring solutions nationwide to NZ construction companies . We are a NZ owned and operated business, we draw on a specialist team with over 35 years’ experience in engineering, machining, design and manufacture.

Trenchmate are constantly innovating our products using our own engineering department at our purpose-built 1200 sqm facility in Papakura, Auckland. We have Territory Managers based all over the North and South Islands, with satellite yards at bases all around New Zealand.

The design of our shields prioritises strength and safety, the health and wellbeing of our customers is at the heart of everything we do at Trenchmate. This priority stretches all the way from design, through to construction, testing, usage and maintenance. We use aluminium to help reduce weight where appropriate but still maintain a strong focus on strength and safety. With over two decades of use, testing and real-world feedback, our shields have evolved to now sit as the strongest, safest, most user-friendly and safest shields on the market.

We run robust tests on our shields to ensure they not only meet the safety threshold but exceed it by at least 1.8 times. As a safeguard Trenchmate has developed and built an in-house hydraulic press to physically test any new concept shields and existing shields to make sure they are still fit for purpose. We use this to place our trench shields under huge loads in the most extreme scenario.
