Most of the Far North is still without power after a major transmission failure in Auckland on Friday morning.
The outage was caused by a forklift hitting a line to Henderson at the Otahuhu sub station just after 8am on Friday. The other was out for maintenance.
Power is now restored to Whangarei, Dargaville and rural areas served by Northpower.
However the upper half of the region, serviced by Top Energy, is still out.
Top Energy says it hopes to have the power back on by 1pm.
The Marsden Point refinery was also brought to a standstill by the fault, but as a priority industry, it had power restored by 9am.
The refinery operates 24 hours per day and depends on a continuous supply.
NZ Refining says it will take some time to restart all the processes and find out how much product has been lost.
Federated Farmers in Northland says the sooner there is an alternative power line or supply north, the better.
