Homeowners doing their own electrical work
Most electrical wiring work must be carried out by a qualified and licensed electrician. However, under the Electricity Act 1992 (Section 79) homeowners can carry out some domestic electrical wiring work on their own homes. The work has to comply with the Electricity (Safety) Regulations 2010 (Part 5, Regulation 57) and NZECP 51.
- remove and replace fuse links
- connect and disconnect fixed-wired appliances
- relocate existing switches, socket outlets and lighting outlets that are supplied with electricity by tough plastic-sheathed cables
- remove and replace the following fittings, as long as it doesn’t involve work on a switchboard:
- switches, socket outlets and light fittings
- permanent connection units, ceiling roses, cord-grip lamp-holders and flexible cords connected to any of them
- batten holders
- water heater switches
Homeowners can also install, extend and alter subcircuits (including submains), provided that:
- they do not enter any enclosure where live conductors are likely to be present, and
- the work is tested and certified by a licensed inspector before being it is connected to a power supply.
Landlords and business owners cannot carry out electrical work in their rental properties or workplaces unless they have the applicable practicing license(s).
