Northland businesses are unsure whether they'll be insured for last week's power outage.

A pylon tipped over on Thursday after too many nuts were removed from the legs, letting it tip.

Transpower says it is an inconceivable and unprecedented situation, and consumers can apply for compensation.

But NorthChamber Chief Executive, Darryn Fisher says they're still in the dark about what's next.

"I don't know if you can insure for negligence in this respect, so as far as businesses here are concerned - I'm not sure whether they're covered or not."
