The second principle that brings National to support this bill is that it clarifies and enhances property rights by creating a default right to build. It takes power away from town planners and gives it back to the people they serve by clarifying the circumstances in which they can add homes to their own land. And, thirdly, at a principled level, this bill will create more competitive markets in which supply of housing is better able to respond to the demand for where that housing should be, that is: it will allow cities to grow and have more housing where people want to live.
