Custom Rota Moulding
Bring your idea to life with custom rotational moulding made in New Zealand. Our in-house team manages CAD design, prototyping, tooling, and production to deliver precise, durable parts that fit first time. We optimise materials (including UV-stabilised resins), wall thickness, and integrate features like bosses, inserts, baffles, and mounting points to cut assembly time and boost reliability.
From one-off prototypes to dependable low–medium volume runs, we deliver consistent quality and on-time production. Applications include marine tanks, live bait systems, industrial reservoirs, enclosures, and specialty components—engineered for strength, serviceability, and clean installation. Work directly with our engineers, keep lead times tight, and partner with a local team that stands behind the result.

Testimonials
Really appreciate the excellent service provided by Jared and the team. I had a cracked seat from a boat I bought a year and a half ago and they sent me a replacement under warranty, which I was pleasantly surprised with as I had assumed it was out of warranty. Super stoked!

“The relationship with Hi Tech has allowed us to grow both businesses in terms of designing and building new product ranges for both companies. We have found their service absolutely great and we get the product when we need it . . . They are keen to do the extra little bit and offer solutions that may not be thought about at the start of the project.”

Bevan, Jared and the team are awesome to work with when it comes to experimenting with new products - just brilliant. The benefits just go on and on. They always meet the deadline when we want something done. Their professional approach to accuracy is extremely important for us and as a result we just wouldn’t want to go anywhere else . . . Their input and technical knowledge . . . you just can’t buy that knowledge.
