Labour's Housing spokesman Phil Twyford said the survey results suggested New Zealanders had "gone over the tipping point on this".
"Even people who own their own homes who benefit from rising prices can see that it's bad for their kids and their grandchildren and bad for New Zealand."
"It's a risk to our economy, and it's a major driver of inequality, between rich and poor, owners and renters, young and old and Auckland versus the rest of New Zealand.
Mr Twyford said it was going to take "bold reform like a capital gains tax and building large numbers of affordable houses" to address the problem.
Housing Minister Nick Smith said he was not surprised by the survey's findings.
"It's why housing reform is such a high priority for the Government. All the long-term data points to being out of kilter and the connection with house price bubbles and the global financial crisis, rightly is raising concern about its broader impact on people's financial security."
Dr Smith said concerns were not just about high prices "but a nervousness that if it drops significantly that has a huge impact on people's equity".
"The concern about the next generation being able to pull together a deposit and to reasonably get on to the housing ladder is very legitimate. There's no question that it is tougher today than 25 years ago. What I have confidence in is the Government's broad programme of measures that I think will make the material difference to improving that."
