Where the facts come from
Licensing and certificates come from the Electrical Workers Registration Board (EWRB) and its public register. Electrical safety and homeowner work come from WorkSafe New Zealand's Energy Safety guidance. Rentals come from Tenancy Services, building rules from MBIE Building Performance, and smoke alarm advice from Fire and Emergency New Zealand.
Power cuts and connections come from the Electricity Authority, Electricity Networks Aotearoa and lines companies' own pages, such as Vector, Powerco, Orion and Unison. Consumer rights come from the Commerce Commission, Consumer Protection and the Disputes Tribunal, and EV charging from EECA's Gen Less and WorkSafe.
Each fact is stored with the page it came from and the date we read it. The first full round was read on 28 October 2026.
When an official page wouldn't load
Some official sites blocked our reader, including the legislation website and WorkSafe's. Where that happened, the fact came from search results limited to that official site, and it's marked as weaker in our records.
We haven't read the Electricity Act or the Electricity (Safety) Regulations directly. So we don't quote maximum penalties from them, and homeowner work is described exactly as WorkSafe words it, never more loosely.
Rules we write by
- New Zealand rules only, in the words Kiwis and the regulators use: lines company, RCD, practising licence, 111.
- No prices for electrical work. A written quote from someone who's seen the job beats any figure we could print.
- Homeowner work comes with its limits: a home you own and live in, unpaid, nothing on the switchboard or meter, and new wiring tested and connected by a licensed electrical inspector.
- Rentals and new builds stay separate. Rental smoke alarm rules come from Tenancy Services, and the rules for new homes come from the Building Code.
- Dates go with rules. The wiring rules change on 12 November 2026, and we say what that does and doesn't mean for existing homes.
- No grant, approval, review or number we can't point to a source for.
Gaps we've left on purpose
We couldn't confirm from an official page whether hard-wired or interconnected smoke alarms must be fitted by a licensed electrical worker, or who may legally install a heat pump. So no page here says either way.
We found no government grant for home EV chargers, but not finding one doesn't prove there isn't one. So we don't promise a grant, and we don't claim there's none.
Who writes our pages
The Sparky Next Door team writes every page and checks each fact against its source before it goes up.
The electricians we match don't write, edit or approve our guides, and no product maker has paid to be mentioned.
