THE FATBOY SHOW : New Zealand MPs disrupt parliament with haka to protest Indigenous treaty bill.

New Zealand's parliament was briefly suspended on Thursday after Maori members staged a haka to disrupt the vote on a contentious bill that would reinterpret a 184-year-old treaty between the British and Indigenous Maori.

First signed in 1840 between the British Crown and more than 500 Maori chiefs, the Treaty of Waitangi lays down how the two parties agreed to govern. The interpretation of clauses in the document still guides legislation and policy today.

Rulings by the courts and a separate Maori tribunal have progressively expanded Maori rights and privileges over the decades. However, some argue this has discriminated against non-Indigenous citizens.
