"We know losing power is a big inconvenience but we'd like to reassure people that we have crews on standby ready to respond," she said.
"If there is damage to power lines we may need to de-energise electricity circuits to carry out repairs safety."
Anyone affected by power cuts was being urged to stay away from damaged electrical equipment and report issues by phoning 0508 VECTOR.
