Master Plumbers, Gasfitters and Drainlayers NZ Inc is the membership body for plumbers, gasfitters and drainlayers across New Zealand, based on the ground floor at 119 Ghuznee Street in Te Aro, Wellington. It is not a trade firm itself. Its website offers members training, networking and trade deals, and says members' work is backed by a 12-month residential Master Plumbers Guarantee. A search tool on the site helps people find a member plumber, gasfitter or drainlayer in their area. The organisation also runs Masterlink, which it describes as New Zealand's largest group apprentice training scheme for the trade. Recent news on the site includes a 2026–2027 board with Felicity Caird as the first female chair in 125 years.
Reviewers describe mixed experiences. One reviewer's partner asked for a hot water cylinder quote and was told a visit would come first, with a call-out of $170 as at 2026. Another found the team professional and easy to deal with, and a third found the staff good, with a wide range of plumbing fittings and plenty of parking. Among six other plumbers within a kilometre, Southern Plumbing & Gasfitting Ltd, 0.6 km away, has 4.5 from 305 reviews, and Grant Plumbing, 0.3 km away, has 3.2 from 52, so this listing's rating comes from far fewer reviews.
