The Government is poised to announce policy changes it hopes will slow the rate at which house prices have been rising, particularly in Auckland.
Finance Minister Bill English says the Government has been saying for some time that fast-rising house prices are not good for the economy.
"The Productivity Commission wrote a report a year or so ago that pointed out some of the real problems, particularly with housing supply.
"We've been working with councils and officials on solutions to that, and you'll hear more about that over the next couple of weeks."
Mr English refused to say whether the housing related policies will be included in the Budget on 16 May.
