Plumbing pipes and fittings in New Zealand

Updated 11 November 2026

Plumbing pipes and fittings in New Zealand cost from about NZ$1.50 for a PVC waste bend to NZ$139 for a 25 mm uPVC pressure pipe, and a 5.8 m drainage pipe sells for NZ$15 to NZ$40 in these listings. For a price on your exact size and material, send a request on BlaBlaPrice and sellers will reply with their own offers.

What the building rules require

The Building Code sets the rules for plumbing products in New Zealand. From 2 May 2026, every new building consent must use lead-free plumbing products, so check that a fitting is lead-free before you buy it for new work. Products used in buildings covered by the Code must come with compliance documents that the consumer can ask for, so request them from the seller.

Most plumbing, gasfitting and drainlaying work is restricted to licensed tradespeople, and the Plumbers, Gasfitters and Drainlayers Board (PGDB) warns that most of it is illegal to do yourself. You can buy the materials yourself, but book a licensed plumber for the installation. Some manufacturers' warranties depend on this: one 25-year warranty on a complete pipe system applies only when the products are installed to the applicable codes and good plumbing practice.

When to order

New Zealand's seasons run opposite to the northern hemisphere: summer is December to February and winter is June to August. November is late spring, so a job you want finished before the summer holidays needs its pipes ordered now, and a request today leaves time to compare offers.

How pipes are sold and delivered

Sizes are metric, in millimetres, and lengths are in metres. Drainage pipe is listed in 5.8 m lengths and pressure pipe in 6 m lengths, so state how many metres you need rather than how many pieces. Ask whether the price includes GST, and whether the seller delivers to Auckland, Wellington, Christchurch, Hamilton or Tauranga or whether you collect.

What to put in your request

Name the pipe material (PVC, uPVC, copper or stainless steel), its use (waste, drainage, pressure or water supply), the diameter in millimetres and the quantity in metres or pieces. For drainage pipe, add the stiffness class such as SN6, and list any fittings and valves you need. Add the brand if you have one in mind, your city or site address so sellers can price delivery, and your budget.

Sending a request on BlaBlaPrice is free for buyers. Describe the job in your own words in the chat and add a photo if you have one. The AI reads the request, asks for anything missing, then looks through sellers' websites and price lists in New Zealand and shows you the prices and businesses it finds. Registered sellers reply in the chat with their own offer, price, terms and delivery. Your contact details stay hidden: you decide with whom to exchange them.
