Many rural households were without power for up to four days after Cyclone Dovi, which swept across the country in mid-February.
A spokesperson for Vector says that in severe storms with widespread damage, it usually takes several days to physically assess damage and restore power.
He says the delay in restoring power was driven by the sheer volume of damage the electricity network sustained across the region.
“There could still be cases where individual households may have suffered damage to their service line, which is the power line that connects their house to the network,” he says.
“These lines are the homeowner’s responsibility to repair and while our crews may be able to make some repairs to these individual service lines if they are straightforward, in most cases customers will need to contact their electrician to complete the repairs.”
