Hundreds of customers remain without power, but thousands have had electricity restored after dual events caused significant outages in the deep south today.

Transpower NZ, the national grid owner, experienced a significant issue at lunchtime today, which meant supply to most of Southland was cut for around 2 hours. Approximately 25,000 customers were without power as a result.

Meanwhile, stormy conditions earlier on Sunday and throughout the afternoon, had also caused outages throughout Southland and parts of Otago.

PowerNet estimates 800 customers remain without power while crews work to repair damage; approximately 500 in Southland and 300 in Otago.

PowerNet Operations General Manager Geoff Thorburn said the PowerNet field teams were well prepared for Sunday’s storm.

“We have had crews out since the early hours of Sunday morning, when the winds first hit. They were out working on repairs when Transpower’s issue first occurred and have continued working through this afternoon.”

“Everyone affected by Transpower’s outage will have had their electricity restored by now, unless there is weather-related damage to poles or lines. If you are still without electricity, and you haven’t called us to let us know, do so now on 0800 808 587.”

“We’ve experienced a lot of lightning strikes throughout Southland which can cause significant damage to our electricity infrastructure, and can take quite some time to repair,” he said.

Mr Thorburn reminded people to stay away from downed lines.

“If you come across any storm-related damage today where vegetation or debris is in contact with lines, don’t be tempted to try and clear it yourself. Call 111 if there’s immediate danger – or call us on our 0800 number.”

He also acknowledged the work Southland and Otago residents, businesses, and farmers had put in to prepare for outages – including trimming or removing trees – following last year’s October wind event.

“We know that many of you have been checking, trimming, and cutting down trees that threaten powerlines over the past year, and that will have made a difference today.”

PowerNet staff will continue working on repairs while it remains safe to do so, and as conditions allow. While it is too early to tell whether people may need to prepare to be without power overnight, we encourage people to check their emergency kits.

If you are medically dependent on power and are without electricity, consider activating your emergency plan or reach out to your medical provider for support.
