Post-earthquake Christchurch required massive sewer and stormwater infrastructure repair. While the main rebuild is complete, residential drain repair and upgrade work continues as older pipes reach end of life.
What Requires a Licensed Drainlayer in NZ
Drainlaying is a restricted trade — all work must be done by someone registered with the Plumbers, Gasfitters and Drainlayers Board (PGDB):
- Installing or altering any drain connected to the public sewer or stormwater network
- Septic system installation and repair
- Sewer lateral connections
- Stormwater drainage

Signs Your Christchurch Home Needs Drain Work

- Gurgling sounds in pipes
- Wet patches in the lawn over the drain line
- Tree roots near older clay pipes
- Sewage smell inside the home
A drain camera inspection ($250–$500) is the best first step — it shows exactly what's happening inside the pipes before any digging.
