Which trade, and what to ask for
| Who does it | Ask for | |
|---|---|---|
| The public water main or sewer | Ashburton District Council | Ring the council first, and ask it where its pipe ends on your section. |
| Taps, pipes, toilets, cylinders | An authorised plumber | A current PGDB plumbing licence, plus their supervisor's name if they're supervised. |
| Underground drains | An authorised drainlayer | A drainlaying licence: a plumbing one does not cover drains. |
| Fixed gas pipes and appliances | An authorised gasfitter | A Gas Safety Certificate once the work is connected. |
Ashburton facts that change a plumbing job
A building surge
Stats NZ counts 223 new homes consented in Ashburton in the year to March 2026, up from 152 the year before. The census counted 8,625 private dwellings in 2023, against 8,220 in 2018. New homes mean new drains, and drainlaying is licensed separately from plumbing.
Frosty nights
NIWA puts Ashburton at 51 days a year when the air falls below freezing, against 34 in Christchurch. Outside taps and exposed pipes are worth a look before winter.
Heat pumps and wood burners
At the 2023 Census, 81.2% of Ashburton homes used a heat pump as a main heat source (66.8% nationally) and 41.9% a wood burner (28.2%). Those figures cover room heating only; ask a plumber whether your fire also heats your water before a cylinder is replaced.
Mostly owner-occupied
64% of households owned their home and 10.7% held it in a family trust in 2023. The other 25.3% were not owned by the people living there, against 34% nationally, so if you rent, the repair is usually a job to raise with your landlord.
Before you book
Ashburton District Council runs the water and wastewater network itself. We couldn't confirm its rule on where the council's pipe stops, so for a leak near the street or a blocked sewer, ring the council before a plumber.
For work on your side, check the person's licence on the PGDB register by searching their first and last name. A tick or green in the far-right column means it's current. Our licence check guide has more, and which tradie do I need? helps if you're unsure.

What we would do
Sort out who owns the problem pipe first. Anything in the street or at the toby, ask Ashburton District Council. On your side, decide which trade you need, because a plumber can't legally lay or repair a drain without a drainlaying licence. If you're building, ask for the drainlayer's name as well as the plumber's and check both. When you're ready, we'll match the job to an Ashburton tradie who specialises in exactly that.
