A Te Pati Māori MP has been suspended from Parliament for kicking off a deafening haka in protest of the Treaty Principles Bill. 

Opposition MPs and people in the public gallery joined in, interrupting a vote on the legislation and forcing the Speaker to clear the House.

Newstalk ZB senior political correspondent Barry Soper says today's events were a mess.

"I've never seen anything like it in more than 40 years of covering Parliament - the Speaker lost control, by no fault of his own."
