The ACT Party is proposing altering the Bill of Rights to make housing more affordable.
In a speech to the ACT Auckland Regional Conference on Saturday afternoon, the party's leader Don Brash, said there is no shortage of land in New Zealand.
Yet he says house prices have doubled since the introduction of the Resource Management Act in 1991.
Dr Brash says ACT would push to have the Bill of Rights changed to protect the right to own and use property as the owner sees fit - unless there a physical threat to others or their property.
He says governments would have to show a good public interest reason to interfere with property rights and then acknowledge that compensation may have to looked at.
