Electricians in OtagoBrick villas, frosty valleys and booming lakes towns.
Most of Otago's towns are on Aurora Energy's lines: Dunedin, Central Otago, Queenstown and Wānaka. PowerNet manages the rural OtagoNet network and the Lakeland subdivisions around Frankton, Wānaka and Cromwell, and Network Waitaki covers North Otago. Outages go to them. For the wiring in your home, we'll find you one licence-checked local electrician who does that kind of work.
Faults lines across Otago
Aurora Energy: Dunedin, Central Otago, Queenstown, Wānaka
24/7: 0800 22 00 05. Check its outage list first. If only your home is off, Aurora suggests checking your switchboard and then contacting your retailer.
PowerNet: Lakeland subdivisions and West Otago
24/7: 0800 808 587. Its outage map only shows faults on key parts of the network, so one affecting a few homes may not appear.
Network Waitaki: Oamaru and North Otago
Emergency faults: 0800 440 220. It posts significant unplanned outages on its Facebook page rather than its website.
Rural South Otago
The OtagoNet network, from Owaka to Shag Point and Lawrence, is managed by PowerNet. If you're unsure of your number, the ENA lines company map shows it by address.
The poles on your land may be yours
Aurora says property owners are responsible for the service line from where it crosses the boundary, including low voltage lines and poles on their land, and it recommends having them inspected every five years. PowerNet says much the same: you own the service lines, poles, cables and fuses on your side, up to an isolating fuse on the boundary or the nearest pole.
On a lifestyle block or a long driveway, that can be a fair bit of line. A licensed electrician can check it and tell you what, if anything, needs doing.
Tell Aurora before the big stuff goes in
Aurora needs an application to alter a connection, and that includes notifiable loads like EV charging, generators and heat pumps. You start with a registered electrician, who registers the job with one of Aurora's Approved Network Contractors. Aurora says you shouldn't apply direct.
That matters here: at the 2023 Census, 70.22% of Queenstown Lakes homes used a heat pump. If you're adding one, or an EV charger, get the application sorted before you buy.
Storms, old brick villas and cold valleys
The 23 October 2025 storm left more than 16,000 Aurora customers without power at its peak, mostly in Dunedin, after trees broke lines from Berwick to the tip of the Otago Peninsula. PowerNet called the same storm the biggest event in its history.
Heritage New Zealand says most of Dunedin's historic housing is villas from the 1870s on, and that the city is notable for brick houses. About 2,700 South Dunedin homes sit less than 50 cm above sea level on soft ground. In an old, damp house, an electrical inspection is a sensible first step.
Inland it's cold and growing. Alexandra averages 92 nights a year below freezing, and Queenstown Lakes went from 11,190 occupied homes in 2013 to 17,397 in 2023.
Checking who you hire
Every licensed electrical worker has a licence ID, and a digital one carries a QR code you can scan to go straight to their profile on the EWRB public register (how to check). We have local pages for Dunedin, Mosgiel, Queenstown and Wānaka.
Our take for Otago
If you've got your own poles and lines, get them checked, and Aurora's every-five-years suggestion is a good rhythm. Adding a heat pump or charger? Have the electrician sort the Aurora paperwork first, so the install isn't held up.
Want a specialist to sort it?
Tell us the job and your postcode. We match the licence-checked local electrician who does this kind of work, and they call you. No ring-around, and your number goes to them alone.

Questions
Straight answers.
Is my Frankton or Wānaka subdivision on Aurora?
Maybe not. The Lakeland Network, managed by PowerNet, runs subdivisions such as Shotover Country and Hanley's Farm in Frankton, Northlake in Wānaka and Wooing Tree in Cromwell. Faults there go to 0800 808 587.
Can I trim trees near the power lines myself?
Not near Aurora's lines: only approved utility arborists may trim within 4 metres of one. On your own service line, PowerNet says trees must be kept at least half a metre away, and trimming should be done by an experienced, qualified contractor.
