Housing developments north of Auckland could soon be charged higher targeted rates to help fund infrastructure.
The government is working with the Auckland Council to see if such targeting of rates can be done under current law.
Finance Minister Steven Joyce said the council had said it could not afford the trunk infrastructure, such as main pipes and roads, to connect a large area of land that had been earmarked for housing growth during the next 20 years.
"It's out the back of Orewa and those sorts of places," Joyce told Radio New Zealand. "The idea would be you would get a targeted rate across that land up there and that would be an income stream that would pay the cost of some of that infrastructure."
Asked if a law change would be needed, Joyce said that was being worked through.
