"I would appeal to these people – do some basic checks first. You wouldn't call an ambulance if it's not an emergency, so consider if you really need help."
The power remains out in parts of West Auckland, with isolated outages in some suburbs.
E tū said the common feedback from its members is that this is the most extensive damage they have seen resulting from large trees being ripped out of the ground and over the lines.
Gallagher said Vector and their contractors, Northpower and Electrix had brought in significant manpower from outside of the Auckland region and crews were working long hours to get the power back on.
"We'd congratulate our many members working on this. They've been working basically non-stop since last Tuesday," he said.
"In some cases, guys have had to be stood down because they've reached their fatigue hours – they're working about 70 hours a week."
He said the safety of the crews on the ground is absolutely paramount for all concerned.
This morning Vector said those without power and/or hot water due to the storm is still between 500 to 1,500, but that number will continue to fluctuate due to weather conditions and ongoing tree fall which is causing new or additional damage.
