Thousands of Aucklanders are in for a shock when Mayor Len Brown unveils a new rates system tomorrow.
Details are being kept secret, reserved, but Mr Brown told the Herald he expected a "very noisy" reception from ratepayers on the losing side of the new system.
As Mayor of the Super City, Mr Brown has the political challenge of changing from the current medley of eight different rating systems to a single system next year.
"We know there is going to be a significant proportion of the population who will get a rates increase and some who will get a rates decrease," he said.
Details of Mr Brown's proposals will be presented to the strategy and finance committee on the same day Auckland property owners begin to receive their latest valuations.
