Wellington Mayor Tory Whanau believes she still has a majority of one vote in favour of selling the council's stake in Wellington Airport - but told Nick Mills she isn't sure if the next vote will succeed.

"We check it every week and people flip-flop. That's the problem." 

The controversial idea passed during the council's long-term plan vote but will come back to the council for a second vote in December.

Multiple councillors now say there is a majority against the vote.

"It's going to be really difficult. Just like the [long-term plan], it takes a lot of political management," Whanau said. 

"It's been a yes up until this point. We have councillors who have changed their mind, you have to ask them. If they want to be irresponsible with our finances, that's on them."  

"I don't understand why you don't interrogate them as much as you interrogate me."  

Whanau also spoke to Nick Mills about the state of roading changes on Thorndon Quay, the idea of a New Year's Eve party on Courtenay Place, and the state of Wellington Water.
