On the flip side, several areas have sizeable rates cuts, including Great Barrier and Waiheke Islands, Rodney and Papakura.
Today councillors will consider options to lessen the pain, although officers are recommending no assistance so everyone on similar value properties pays the same rates.
The issue has been made more difficult because there are still 30,000 ratepayers who have not yet been moved over to a new single rating system for the Super City after a three-year transition period.
One option is to cap rates increases at 10 per cent next year.
This would result in an additional rates increase of 3.7 per cent, or an average household rates increase of 9.3 per cent, according to a report by a council officer.
Last week, the council bowed to a revolt by Local Boards over a 40 per cent cut in new spending on parks, community services and leisure activities and opted for 3.5 per cent rates increases over the next decade.
The latest inflation figure stands at 1 per cent.
Mayor Len Brown, who promised to hold rates at 2.5 per cent this term, voted with a majority of councillors for the 3.5 per cent increase.
