About licences
When you contract an electrical worker always ask to see their licence ID. This can be either a physical or digital licence. This is proof that the worker is currently competent to do electrical work safely.

When you look at the licence ID check that the licence hasn’t expired and that the photo matches the electrical worker.
Electrical Worker Public Register
You can search the Electrical Worker Public Register to check the licence hasn’t been suspended. If they show you their digital licence, you can scan the QR code to go straight to their profile on the register.

The licence will list the “classes” of registration the electrical worker holds. The classes specify the electrical work the holder is licensed to undertake. The New Zealand Gazette explains the scope of each class.

If you come across someone who is claiming to be a licensed electrical worker when they are not, carrying out prescribed electrical work when they are not licensed or an employer who has engaged an unlicensed person to carry out prescribed electrical work you can report them. There is information about reporting someone doing unlicensed work here.
