There's confusion over the size of Wellington City Council's fiscal hole. 

The council is scrambling to fill a $400-600 million shortfall in its 10 year budget to mitigate its insurance risk, amid threats of Government intervention. 

But Councillor Nicola Young told Mike Hosking the council doesn't have a clue how much money it actually needs. 

She says they've been told by council officers figures like $200, $400, and $600 million, so the council is aiming to find $500 million.
