Increasing the Uniform Annual General Charge (UAGC) would simply see more people facing double-digit rates rises.

There have been calls to increase the charge as part of implementing the government-imposed single rating system for Auckland but the Mayor says this would make things worse rather than better.

"The government’s Auckland Council legislation requires a single rating system with the setting of a single UAGC for the region," says Len Brown.

"Increasing the UAGC would simply mean more people across the region facing 10 per cent plus rates increases."

Under the existing $350 UAGC, 127,165 residential ratepayers face increases of more than 10 per cent because of the impact of amalgamation.

At $450 that number increases to 129,585 and at $750 that number jumps to 170,847.

"It is also wrong to say that council’s investments have caused people’s increases. The fact is that we could have set a zero-budget and cut things like our investments in trains, libraries and parks, and many ratepayers would still be facing substantial increases.

"The average increase across the region is 3.6 per cent. The fluctuations above or below that mark were locked in the moment the government passed legislation setting up Auckland Council stipulating capital value as the basis for setting rates.

"The amalgamation was a massive challenge in all sorts of ways, not least of all rates, but we have brought in transition policies to smooth out any change and in the end we will have a fairer system where homes of the same value will pay the same rates, wherever they are in the region," says Len Brown.
