When to Call an Electrician (and When You Can DIY)
Changing a light bulb is fine. Replacing a light fitting probably isn't. Here's a clear guide on what New Zealand law says you can do yourself and what needs a licensed sparky.
In New Zealand, the Electricity Act is clear: most electrical work on fixed wiring must be done by a licensed electrical worker. That means the wiring inside your walls, your switchboard, and most fittings are off-limits for DIY.
Here’s a rough guide:
You can do yourself:
- Change light bulbs (including LEDs into existing fittings)
- Replace a broken plug on a portable appliance
- Reset a tripped circuit breaker (once — if it trips again, call us)
You need a licensed electrician for:
- Any new wiring, including adding a power point or light fitting
- Replacing a power point, light switch, or fitting (even like-for-like)
- Switchboard work of any kind
- Installing or connecting any fixed appliance (oven, rangehood, hot water cylinder, heat pump)
- EV charger installation
The reason is simple: incorrect wiring kills people. It also voids your home insurance. Don’t risk it.
If you’re unsure, call us. We’ll tell you honestly if it’s something you can handle or if you need a sparky. No charge for that conversation.
