Mega-moves to halt a housing bubble.
Almost $4 billion is going into a fund for housing infrastructure, and the Government's doubling the bright line test to 10 years.
It's also lifting the ceilings for income and regional house price caps for first-home buyers.
Finance Minister Grant Robertson says we can't afford to allow spiralling house prices to put our economic recovery at risk.
One Roof property commentator Ashley Church told Kerre McIvor if the Government wanted to reduce house prices , it's already failed.
"Nothing in this package actually reduces house prices, including things like the bright-line test measures, which will make absolutely no difference."
