Dozens of homes were without power late on Wednesday night in parts of Queenstown.
An Aurora Energy spokeswoman said the lines company was responding to two separate faults, one affecting Dalefield and Arthurs Point, and one affecting Fernhill.
The outages were unrelated.
''Aurora Energy can confirm that 55 electricity customers have been affected in the Dalefield and Arthurs Point areas.
''At this stage we don’t have any more information regarding estimated restoration time or the number of customers affected in Fernhill,'' the spokeswoman said.
The crews were working in challenging weather conditions, she said.
