Skilled plumbers and drainlayers scheme expands
23 Apr 2026
A self-certification scheme allowing skilled plumbers and drainlayers to sign off their own work is being expanded to cover more residential work and some commercial activity, Building and Construction Minister Chris Penk says.
“Trusted tradespeople want to get on with delivering the homes and infrastructure New Zealanders need, but too often they are slowed down by lengthy inspection delays that hold back productivity, pushing up the cost of building” Mr Penk says.
“The Government is progressing the Self-certification by Plumbers and Drainlayers Bill to put responsibility into trusted tradies’ hands. It will speed up building by allowing approved plumbers and drainlayers with a proven track record to certify their work is consistent with the building consent.
