Compliance
What electrical work legally needs a licensed electrician in NZ?
It is tempting to save money by doing electrical work yourself, but in New Zealand the rules are strict for good reason. Most fixed wiring has to be done by a registered electrical worker, and getting it wrong can cost far more than it saves. Here is where the line sits.
Prescribed electrical work
Most fixed wiring in a home counts as prescribed electrical work under the Electricity (Safety) Regulations 2010. That means new circuits, switchboard work, wiring in power points and light fittings, and connecting fixed appliances all have to be carried out by a registered electrical worker. It is not a grey area.
What a homeowner can do
The list of work a homeowner may legally do on their own home is short and low-risk: things like replacing a like-for-like ceramic fuse or wiring a plug onto a flexible cord. Anything that touches the fixed wiring, the switchboard or a permanent connection is off the list. If in doubt, treat it as a job for an electrician.
Certificates that come with good work
When prescribed electrical work is done properly, you should receive a Certificate of Compliance (CoC) confirming it is safe and to standard. Higher-risk work also comes with an Electrical Safety Certificate (ESC). Keep these: they are your proof the work was done right, and insurers and future buyers may ask for them.
How to check an electrician is registered
Every registered electrical worker in New Zealand has a number you can check on the Electrical Workers Registration Board public register. Ask for the number, look it up, and confirm the licence is current before the work starts. A genuine electrician will be happy for you to do exactly that.
Common questions
Can I install my own power point to save money?
No. Wiring a power point is prescribed electrical work and must be done by a registered electrician. Doing it yourself is unsafe and can void your insurance.
