A Wellington City Councillor says there are ramifications from the Town Hall renovation budget blowout.

The council today voted to pay up to $147 million to cover cost increases for earthquake strengthening the CBD venue.

The total overall cost could end up as high as $329 million.

Councillor Ben McNulty says it'll take a toll on other things.

"We have to be clear that by doing this Town Hall project and the extra money, we won't be doing other things. We will be taking away from other things that we should be doing."
