Other factors, like new revaluations and the move to a single rating system, would see average increases of 15 per cent or more in many suburbs. Poor suburbs like Mt Roskill, Avondale, New Lynn, Mangere, Otahuhu, Beach Haven and Glenfield would be among the hardest hit.
About 4000 households would face 40 per cent-plus rates increases, but rates would decrease in areas like Waiheke Island and Rodney.
It is a total nonsense for Auckland councillors to abstain on the budget, said Auckland Chamber of Commerce chief executive Michael Barnett. He said the budget was not fit for purpose and councillors should not abstain.
Councillors still thinking of abstaining are Cathy Casey, Ross Clow and Wayne Walker. Mike Lee said he planned to vote after he hears and reads what is reported at tomorrow's governing body meeting.
Chief finance officer Sue Tindall said if the budget was not passed by June 30, rates could not be struck for the new financial year, beginning on July 1.
"This would give rise to a potential issue with respect to securing cashflow. Council would be obliged to notify bankers and other relevant financial agencies," she said.
Ms Tindall said the Office of the Auditor-General had completed the audit process for the budget and councillors "would have no reason not to adopt the plan" after making budget decisions in May.
