Why Christchurch differs
Christchurch sits near or below the national average, but TC2 and TC3 land can add tens of thousands to foundations, so check the Tech Category before you commit.

Rewiring an existing house doesn't usually need a building consent. The electrician must issue an Electrical Certificate of Compliance for the work. Adding new structural penetrations or significant changes may need consent.
Questions to ask before you sign
- Are you replacing the switchboard? Recommended for any pre-2000 house.
- How many outlets and points are included?
- Will you issue an Electrical Certificate of Compliance and Electrical Safety Certificate if needed?
- Who patches the GIB after the cables run?
- What's the warranty on the install?
Christchurch rewire a house: common questions
- When does a house need a rewire?
- Pre-1970s houses on original wiring usually do — old insulation degrades, no earthing, no RCD protection. 1980s-90s houses with VIR or rubber-insulated wiring also benefit. Houses post-2000 rarely need a full rewire unless damaged.
- Can I do a rewire myself in NZ?
- No — almost all rewire work is prescribed electrical work requiring a licensed electrician. A homeowner can plan and arrange, but the actual wiring must be done by an EWRB-registered person who issues the Certificate of Compliance.
Before you pay anyone, check who they are.
Check the company that quoted you: company status, registration and what's on the public record, from the official NZ sources.
