AI summary

Renovating a bathroom in NZ may require building consent, depending on the scope of work.

You likely won't need consent for like-for-like fixture replacements or cosmetic updates. However, consent is generally mandatory for:

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

- Significant drainage alterations

- New tiled wet areas or walk-in showers

Always confirm requirements with your local council or a licensed building practitioner. Proceeding without required consent risks fines, insurance invalidation, and future sales complications.
