AI summary

Renovating a bathroom in NZ may require building consent. While cosmetic updates or like-for-like fixture replacements are often exempt, consent is typically mandatory for:

- Structural changes (e.g., moving walls)

- Significant drainage alterations

- New tiled wet areas or adding a new bathroom

Proceeding without necessary consent can lead to fines and issues with insurance or future sales. Always confirm requirements with your local council or a Licensed Building Practitioner, as all work must meet the NZ Building Code.
