Burning smells, sparking and tripping breakers need an electrician now. Here are the signs you need an electrician urgently, and the ones that can wait.
Call an electrician straight away for a burning smell, sparking, a breaker that will not stay reset, exposed wiring or any electric shock, because these point to an active fault or fire risk. Warm switch plates, occasional flickering and an old fuse-based switchboard should be inspected soon, but they rarely need an urgent after-hours callout.
The clearest signs you need an electrician now are a burning smell, sparking, or a breaker that will not stay reset. These point to an active fault, and the safe response is to stop using the circuit and get a registered electrician in.
Electrical problems do not always announce themselves that clearly. A slightly warm switch plate or lights that flicker now and then deserve a booked inspection, but they are not usually an emergency. This guide separates the two, so you know when to call urgently and when a routine booking is fine.
These signs mean something in the wiring or an appliance is failing while it is live. Do not wait for a convenient time.
Your priority is to cut the risk without putting yourself in danger. If there is visible fire or smoke, leave the house and call 111 first, then deal with the electrician.
These are worth getting looked at within days or weeks. They rarely need an after-hours callout, but they should not be left for years.
New Zealand allows homeowners to do a limited amount of electrical work, but only in a home they own and live in, with no payment or reward. WorkSafe lists the permitted jobs, such as replacing switches, socket outlets and light fittings, as long as the work does not involve any switchboard. It also says to never do any work on a switchboard apart from replacing fuse wire or fuse cartridges.
Anything beyond that list, including new circuits and most fault-finding, needs a registered electrician. Landlords, tenants, employers and employees cannot do their own electrical work in a rented or workplace property unless they are registered. A fault that shows up as heat, smell or sparking is not a DIY job even where a simple fitting swap would be allowed.
For urgent work, ask whether the electrician is registered, whether they can attend today, and what a callout and assessment will cost before they arrive. For fixed wiring work, ask for the Certificate of Compliance when the job is finished, as electricians are required to supply one for that kind of work according to WorkSafe's guidance on getting electrical work done.

Sometimes. WorkSafe allows homeowners to replace switches, socket outlets and light fittings in their own home without payment, provided the work does not involve any switchboard. Anything else, and any work in a rental, needs a registered electrician.
A breaker that trips repeatedly is protecting you from a fault. Unplug what was last connected, reset it once, and if it trips again straight away, stop resetting it and call a registered electrician.
Treat any unexplained burning smell near an outlet, switch or switchboard as an emergency. Switch off that circuit at the switchboard if you can do so safely, and call an electrician immediately. If you see flames or smoke, call 111.
There is no routine inspection requirement for most existing homes. Older houses, fuse-based switchboards and homes about to be renovated or bought are the cases where a check by a registered electrician is most worthwhile.
