Do I need a building consent to renovate a kitchen in NZ?
Short answer
A like-for-like kitchen makeover — new cabinets, benchtop, splashback and paint in the same layout — usually doesn't need a building consent. You'll generally need one if you move or add plumbing or gas, or remove a load-bearing wall. Electrical, plumbing and gas work must still be done by registered tradespeople.
Key facts
- Cosmetic refresh in the same layout: usually no consent
- Moving or adding plumbing or gas: usually needs consent
- Removing a structural wall: needs consent and an engineer
- Electrical, plumbing and gas work must be done by registered tradespeople regardless
What's usually exempt
Replacing cabinetry, benchtops, splashbacks, flooring and appliances in the same positions is normally treated as cosmetic work and doesn't need a building consent.
What triggers a consent
You'll generally need a building consent if your renovation:
- Relocates the sink, dishwasher or gas hob (new plumbing or gas runs)
- Removes or alters a load-bearing wall to open up the space
- Changes the building's structure or external openings
Who must do the work
Regardless of consent, electrical work must be done by a registered electrician, and plumbing/gas by registered tradespeople who certify their work. Structural changes are restricted building work and need a Licensed Building Practitioner.
