AI summary

Renovating a bathroom in NZ may require building consent. You likely won't need it for cosmetic updates or like-for-like fixture replacements. However, consent is mandatory for structural changes, significant drainage work, and new tiled wet areas requiring waterproofing.

Failing to get consent risks fines and insurance issues. Always confirm requirements with a licensed plumber, builder, or your local council before starting. The process involves inspections and a final Code Compliance Certificate (CCC).
