Rewire a House cost in Dunedin (2026)
Typical Dunedin range
$8,000 – $69,000
Most Dunedin projects land around $17,000 – $29,000. Prices run near the national average.
Why Dunedin differs
Dunedin runs a little below the national average, but hill suburbs add retaining and the colder H1 climate zone lifts the insulation spec.

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?
Dunedin 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.
