UPDATE: Early morning power outage affects 1000

NOW: Essential Energy have upgraded the estimated residences affected by the ongoing power outage to 1022 and have said the cause of the incident is 'wildlife in wires'.

There is still no confirmation on when the power will be restored as crews continue to work on the situation.

BEFORE: Just before 5am on Thursday morning around 1200 residences were left in the dark when an 'unknown cause' resulted in a power outage.

There were two large sounds similar to electrical feedback causing the power to go on and off before it went completely dark.

Essential Energy have said they are investigating the cause and will know more soon.
