Complete plumbing, gasfitting and drainage solutions for new residential and commercial construction projects across Hamilton and the Waikato.
Building a new home or commercial property in Hamilton? Plumbway Ltd provides end-to-end plumbing, gasfitting and drainlaying services for new builds throughout the Waikato region. From the initial planning and design phase right through to sign-off, our registered team works alongside builders, project managers and homeowners to ensure every aspect of the plumbing installation is completed to the highest standard and in full compliance with New Zealand building codes and council requirements.
Our new build plumbing service covers every stage of your construction project. We begin with pre-construction planning, working with your architect or builder to design efficient pipe layouts that minimise waste and maximise performance. This includes underground drainage and sewer connections, storm water systems, water supply pipe installation, and gas line fitting for hobs, califonts and central heating. We handle all council inspections and ensure drainage work meets local Hamilton City Council and Waikato District Council standards. Whether it is a single residential home in Rototuna, a duplex in Flagstaff, or a multi-unit commercial development in Te Rapa, Plumbway has the experience and resources to deliver on time and on budget.
The fitout stage is where your new build starts to feel like home. We install all kitchen and bathroom plumbing fixtures including sinks, tapware, dishwasher and washing machine connections, toilets, showers, baths and vanity basins. Our team ensures hot water cylinders or continuous flow systems are correctly sized and installed for your household needs. We also fit gas appliances such as gas hobs, fires and water heaters, providing the necessary gasfitting certification for a safe and compliant result.
Plumbway Ltd is a locally owned Hamilton business with a strong reputation for quality workmanship, clear communication and reliable service. We are fully registered plumbers, gasfitters and drainlayers, and we stand behind every installation with a quality guarantee. Our team understands the unique requirements of building in Hamilton and the broader Waikato area, from soil conditions that affect drainage design to the latest energy-efficient hot water solutions.

A plumber is needed at two main stages in a new build. The first is the rough-in stage — before concrete is poured (for slab foundations) or before wall linings go in (for timber frame) — where we install all the pipes, drain lines and waste stacks. The second is the fit-out stage after linings are complete, where we install all the fixtures: toilets, basins, shower valves, tapware, the hot water cylinder and kitchen sink connections.

We handle everything from groundworks through to council inspection.
Yes. All our new build plumbing work is carried out to meet NZ Building Code requirements. We coordinate with your building consent authority for the required plumbing inspections at key stages (typically rough-in inspection before linings, and final inspection before code compliance certificate). Our licensed plumbers and gasfitters sign off the required producer statements.
