Auckland councillor Dick Quax, an outspoken critic of Mayor Len Brown, has called on him to withdraw from hosting Prince William and wife Catherine early next year.
The couple and their baby George will visit New Zealand in April.
Yesterday, Quax said Brown should not be greeting the royals after his two-year extramarital affair with Bevan Chuang and a review that found he had accepted free hotel rooms and upgrades.
"I'd be absolutely horrified if he was the face and the representative of Auckland meeting Prince William, his wife and their baby."
Quax and fellow councillors Chris Darby, Linda Cooper and Bill Cashmore said they did not expect Brown to be mayor a year from now.
