The National-led Government said development contributions had risen more than any other component of housing costs, from an average of $3000 to $14,000 in the past 10 years.
Its law changes would narrow the charges councils could demand from developers. Auckland would not be able to levy for community infrastructure apart from public toilets, playgrounds and community halls.
While it could still charge for core infrastructure such as transport, water and sewerage, it would have to fund community facilities such as parks, sports grounds and libraries with alternative sources such as rates.
Auckland Council said in its draft submission that it had planned $480 million in new community infrastructure in the next 10 years, and this would be paid for with development contributions.
"The bill ... leaves the council with two choices - either have inadequate infrastructure or fund the cost of borrowing from existing ratepayers."
If the proposals went ahead, the council predicted, the cost of paying for the community infrastructure, with a new appeals process, would lead to an 8.5 per cent rise in the average rates bill by 2021/22.
This would shift the cost of new development from new ratepayers to existing ratepayers, who were not responsible for the new growth.
The council said the community assets were not "nice to haves" but essential to the success of new communities and residents' well-being.
Dr Smith said the council "has got to decide whether it is serious about improving housing affordability within its city. Councils do have to make those hard choices."
The council said the Government should at least guarantee contributions allocated to projects already under way would not be cut.
