Act Leader David Seymour says MPs shouldn't take a position on his Treaty Principles Bill until it's been through the Select Committee process

Submissions for the bill close at midnight tonight.

Despite National and New Zealand First promising to vote down the bill at second reading, Seymour says politicians should listen to submitters before making up their minds.

Given everyone has to live under our constitution, he says everyone should have a say on what kind of constitution that is.
