But Cr Glenn Livingstone said he would be seeking answers from council chief executive Tony Marryatt over why the town hall was insured for much less than its repair cost.
He believed ratepayers would end up paying for the difference between the repair cost and the insurance cover.
"Personally I don't think it's fair that ratepayers should fund the shortfall, especially with everything that's happened with the earthquakes and ratepayers having to pay for other things in the city," he said.
"The problem is that the town hall is valued so highly by the community. It's the price we pay for something people really want.
"I will be asking Mr Marryatt if there are any other creative ways that the shortfall could be funded and I would like to know why the town hall was under insured because the cost to ratepayers is very high. It is a lot of money for ratepayers to cough up," he said.
The committee decided against a council staff recommendation to fix only the auditorium and demolish the rest of the town hall.
