If you’re planning to install solar water heating you will need building consent.
You’ll also need consent if you are installing a wetback connected to a fireplace.
You won’t need consent for an authorised person to repair or replace an existing water heater when using comparable materials in the same position. This also includes any existing wetback and solar water connections.
For full guidance on exempt work, please refer to the government guidance.
Government guidance: Plumbing and drainage work that doesn't need a building consent
Apply for building consent
All building work in New Zealand must comply with the building code, even if it doesn’t require a building consent. This ensures buildings are safe, healthy and durable for everyone who may use them. For everything you need to know about building code compliance or anything else to do with building in New Zealand, see the government guidance available on the Building Performance website.
