Rewiring a house in New Zealand typically costs NZ$8,000–$18,000. A small unit or partial rewire can be NZ$5,000–$9,000, a standard 3-bedroom home is around NZ$10,000–$15,000, and a large or two-storey home often runs NZ$15,000–$25,000+. The biggest variables are the number of points, whether walls are open or lined, and switchboard upgrades. These are guide figures and include 15% GST.
How much does it cost to rewire a house in NZ?
- Small unit / partial rewire: NZ$5,000–$9,000
- Standard 3-bedroom house: NZ$10,000–$15,000
- Large or two-storey home: NZ$15,000–$25,000+
- Switchboard upgrade (often required): NZ$1,000–$3,000
- Per power point or light point: NZ$120–$200 installed
These are guide ranges for registered electrical work. An occupied home with lined GIB walls costs more than a gutted renovation because cabling has to be fished through cavities.
What affects the price
- Access: open or stripped walls are far cheaper than fishing cable through finished walls and insulation.
- House size and number of points: more rooms, lights, socket-outlets and data points = more labour and cable.
- Switchboard and safety: older homes usually need a new board with RCDs to meet AS/NZS 3000, plus a Certificate of Compliance (CoC) and Electrical Safety Certificate (ESC).
- Single vs two storey: upstairs runs and roof-space access add time.
- Extras: data/TV cabling, LED downlights, smoke alarms, heat pumps and EV charging add to the total.
How to get an accurate rewiring quote
A real price needs a site inspection. An electrician has to see the switchboard, wall access and the number of points before committing. Ask for an itemised quote that separates materials, labour, the switchboard and any making-good, so you can compare like for like. Tradies who quote on the spot win more of this work; with Insta Quotes a Kiwi electrician can describe the job and send a professional, itemised quote (NZD, 15% GST) in under 30 seconds.
