The Act Party wants property rights added to the Bill of Rights Act to allow owners of private property to do as they please with their land.
In the first of his party's campaign speeches, leader Don Brash again referred to government regulators as "little Hitlers" and championed as little government interference as possible.
He said New Zealand could be a country "where people are free to do as they please on their own property - provided it doesn't damage the property of others", or it could regress "down to a black hole where little Hitlers tell you what colour you may paint your house".
Mana Party leader Hone Harawira has compared Dr Brash to Hitler for his polarising views on Maori, which Dr Brash has rejected.
Dr Brash said the Act Party wanted to amend the Bill of Rights Act to include property rights.
