"During power outages, Unison regularly advises the following safety precautions:
"Never touch wires or lines lying on the ground, over fences, hanging from poles, or objects such as tree branches that may be touching them. Fallen lines or wires may still be carrying an electrical current and could shock, injure or even kill if touched.
"Turn off the power at the main switch if you suspect any low power or a damaged supply to your home. If the power goes out, turn off electrical appliances, but leave one light on to indicate when the electricity supply is restored."
Meanwhile Horizon Energy has restored power to all customers on Troutbeck Road, Galatea.
"We expect supply to customers in Gow Road, Edgecumbe, be restored within the next two hours," said operations manager Jan Cronje.
"Unfortunately due to the inaccessible conditions the 10 customers in Waiotahi Valley will be without power overnight.
"Horizon Energy apologises for any inconvenience this may have caused and advises all customers to contact their retailers in the first instance and to treat all lines as alive at all times."
