At Fluid, we specialise in delivering practical, cost-effective hydraulic design solutions for commercial, residential, and public sector projects across New Zealand.

With over 25 years of combined trade and design experience in plumbing, gas fitting, and drainlaying, our hydraulic team knows how to bridge the gap between design intent and real-world installation. The result: systems that work reliably—and are simple to install, maintain, and certify.

We collaborate closely with architects, builders, developers, and consultants to ensure hydraulic services are well-coordinated, future-proofed, and fully compliant with local and national regulations. From high-rise apartments and aged care facilities to schools and medical centres, our designs integrate seamlessly with the wider building services package.
