We are HiTech Plastics

We are HiTech Plastics

We are Hi Tech Plastics, New Zealand owned, Hamilton based, and family run. Brothers Jared and Bevan Mills have driven the business with hands-on enthusiasm since their father purchased it in 2002. They have built a reputation for accuracy, reliability, and straight-up service. We source from New Zealand suppliers to uphold quality, and our products are trusted across the country. We supply every boat builder in New Zealand and more than 200 marine dealers nationwide.

Our strength is custom rotational moulding backed by full in-house CAD design, rapid tooling, and precise production. Whether it is a live bait tank, bait board, water or effluent tank, or comfort enhancing seating, we engineer parts that fit first time and lift real-world performance. While the marine industry is our backbone, our expertise now spans many sectors, including underground pipe components, playground equipment, air intake systems, planter pots, RV and caravan tanks, mudguards, pest control traps, and caravan gas covers. This breadth of work has made us leaders in new product design and production.

FAQ

Do you offer custom rotational moulding? What’s the process?

Yes. We handle CAD design, prototyping, tooling, and production in-house. Share your brief or drawings, we’ll refine the design, quote, and schedule tooling. After approval, we produce samples for sign-off, then move into repeatable low-to-medium volume runs.

What are typical lead times and minimum order quantities?

For stocked items, dispatch is usually within a few business days. New tooling and first-off parts typically take 2–6 weeks depending on complexity. Ongoing production runs are scheduled to your needs. MOQs are flexible for prototypes and scale with volume for best pricing.

Are your products NZ-made and certified?

Yes. We manufacture in Hamilton using NZ-based suppliers. Our marine seating meets ABYC H-31 standards, and we offer UV-stabilised and food-grade material options where required.

Can you make custom water or effluent tanks to fit my space?

Absolutely. Provide dimensions, a sketch, or CAD, and we’ll design a tank with the right wall thickness, fittings, baffles, and mounting points for a first-time fit.
