About 4000 households face rates increases of 40 per cent or more next year under a "cold turkey" proposal causing deep divisions among city councillors.
The budget committee yesterday voted 10-7 to implement big rates rises in one hit next year.
The decision will be felt hardest north of the harbour bridge, where 2122 of the 3738 households facing a 40 per cent-plus rates increase are located.
The big rises are at the extreme end of the latest property valuations and the end to implementing a single rating system for the Super City.
