Do I need a registered electrician?
For almost everything, yes. Most electrical work in New Zealand must be done by a registered electrician and certified afterwards. Ask for the certificate of compliance when the job is done.
How much does it cost to add a power point?
It depends far more on access than on the socket. An easy run in an accessible wall is quick, while a point on a brick or plastered wall can take several times as long. That is exactly why it is worth getting a quote rather than a phone estimate.
Can I get a fixed price instead of an hourly rate?
Usually. When you describe the whole job up front, most electricians will quote a fixed price for it. NovaPay asks for the callout, the rate and the expected hours so you can compare either way.
Who installs an EV charger?
