Power has been restored after a major outage that took down traffic lights at two intersections.

Traffic lights were down in Brookfield and Katikati this afternoon.

The PowerCo website initially reported 22483 properties were affected by an unexpected power outage centred in Bethlehem about 2.30pm. In an emailed statement the company later said the actual number initially affected was 18,000.

A PowerCo spokeswoman confirmed just before 4.30pm that the power was back on to all affected.


The source of the outage was still being investigated.

The company apologised for any inconvenience to customers.

People as far north as Katikati reported losing power.

James Wickham, the council's transport operations centre manager, said just after 3pm that traffic lights and lights at a pedestrian crossing were out at the Brookfield roundabout.

He confirmed just before 4.30pm that all the lights were back on.

Earlier he said there was not much the council could do until the power returned, and drivers should follow the usual give way rules for roundabouts.

It was likely there would be some delays at the roundabout.

Of more concern was a pedestrian crossing, which was between a school and a retirement village. As schools let out, drivers should take great care in the area, he said.


If the outage continued the council could install a temporary generator, but that would take two or three hours and would only be used if a prolonged outage was expected, Mr Wickham said.

A signalised pedestrian crossing near the Katikati shops went out, but came back on fairly quickly, he said.

Western Bay road policing head Senior Sergeant Ian Campion said just after 4pm that police had been monitoring some intersections but he was not aware of any problems resulting from the lights going out.

Carol Burborough of Brookfield Primary School said teachers had been concerned when they saw the lights were out at their road crossing.

"But motorists were just so courteous and we were able to cross all the kids over safely."

She said some teachers had gone home early as they could not work on computers without power. "Other than that it's just very dark."


Bethlehem Four Square storekeeper Manpreet Kaur said they had to close the store for health and safety reasons because it was too dark inside. Most of the shops in the vicinity had lost power.

The power came back on for Ms Kaur at 3.30pm.
