Cost drivers
Wet-area waterproofing (E3 of the Building Code) — non-negotiable, professionally laid. Materials and labour usually $2-4k.
Tiling — porcelain $50-150/m² material, $80-130/m² labour. Natural stone $120-400/m² material.
Plumbing — licensed plumber + drainlayer. New layout adds $5-15k easily.
Vanity and fittings — $1,500 for builders' merchant range to $15,000+ for designer.
Shower glass — frameless $1,800-3,500 installed; bi-fold $900-1,800.
When consent kicks in
Replacing fittings in the same location: usually exempt. Moving wet areas (shower, toilet, vanity): usually requires building consent because of E3 (internal moisture) compliance.
All plumbing must be done by a licensed plumber. They must issue a Certificate of Compliance. Don't pay until you have it.
Knowing the rules is half the job. The other half is knowing who you're hiring. Check any NZ builder against the public record: company status, licensing and insolvency notices, from the official NZ sources.
