Call Now — We'll Sort It 0800 322 322Onehunga is a suburb built on rock — literally. Sitting on Auckland's volcanic field alongside Mangere Mountain, the ground beneath Onehunga is basalt lava rock that makes every drainage job a challenge. Add in heritage villas with some of the oldest plumbing in South Auckland, and you've got a suburb that needs a plumber who knows what they're walking into.
Water & Gas Worx handles it all. Drain excavations through volcanic rock, galvanised and lead pipe replacements, gasfitting, and hot water upgrades. Plumbing and gas under one roof. That's the whole point.
Onehunga has a rich history. The old workers' cottages and villas along Onehunga Mall and Church Street date back to the 1860s-1900s. The state houses from the 1940s-1950s further out. And now new townhouse developments are filling in around the edges. Each era brings different plumbing challenges, and the volcanic rock underneath ties them all together.
Volcanic basalt under Onehunga means drain work isn't straightforward. We have the gear to excavate through rock — no surprises, honest pricing that accounts for ground conditions.
Galvanised, lead, and cast iron pipes replaced with copper or PEX. Onehunga's oldest homes need this work done properly — we re-pipe with care and minimal disruption.
Onehunga has reticulated gas throughout. Gas hobs, califonts, fireplaces, heaters — installed, serviced, and certified. Compliance certs on the spot.
Old electric cylinders in Onehunga homes are often 25+ years old and on borrowed time. We replace with electric, gas, or continuous flow — same-day service available.
Old clay drains, tree roots, and scoria backfill — Onehunga's drainage trifecta. We clear, CCTV inspect, and fix the actual problem, not just the symptom.
Onehunga is seeing plenty of new townhouse development. Full plumbing and gas rough-in, plus renovation work on existing villas. We work with builders or direct.
Yep — Mt Wellington, Ellerslie, One Tree Hill, and all of Auckland.

Volcanic basalt. Onehunga sits on Auckland's volcanic field — the same basalt that created Mangere Mountain. You hit solid rock at shallow depths, making drain excavation slower and requiring specialist equipment. We know this going in and price honestly so there are no surprises.
That's bread and butter for us. We install, service, and certify all gas appliances.
Yes. Onehunga has some of Auckland's oldest housing stock, and lead service lines are still present on some pre-1940s properties. We test, identify, and replace lead pipes with modern copper or PEX to keep your drinking water safe.
We quote before we start. Onehunga jobs can vary due to volcanic rock conditions, but we assess the situation properly and give you an honest price. No hidden extras. Call 0800 322 322.
