Labour is attacking the Government, for ignoring what it describes as commonsense solutions to the housing crisis.

Leader Andrew Little has delivered his pre-Budget speech in Wellington, ahead of the Government opening up the books on Thursday.

Mr Little said the Government needs to crack down on housing speculators and land bankers.

"That's why Labour will say to overseas buyers, if you want to purchase a house in New Zealand, you have to add to our housing stock just like they do in Australia."

He said National can't claim economic success if it looks after only the people at the top, rather than addressing the thousands missing out on home ownership, or even with no roof over their head at all.

Mr Little said workers are getting a smaller slice of the pie each year, while those at the top of the chain enjoy the spoils.

He said wage earners got over 50 percent of the share of economic growth under the last Labour Government, but today, it's fallen to 37 percent.

"And if you want to know what that means in practical terms, this year that lost income works out to be roughly 50 bucks a week for the average family."
