Power has now been restored to central Dunedin after a contractor dug through a cable and cut electricity to most of the city's Central Business District.
Aurora energy said the power was cut in parts of the central city and extending suburbs and had affected more than 1500 customers throughout Dunedin.
Spokesman Gary Johnson said the power was restored to all users at 12.37pm.
The power had been out for more than an hour.
"At 11:11am this morning, an external contractor digging in York Place damaged a power cable on the Aurora Energy network causing loss of electricity supply to 1524 consumers in the central business district and City Rise area of Dunedin," Johnson said.
