Hana-Rawhiti Maipi-Clarke did the Haka with her fellow Maori Party members while ripping up an equal rights bill, shutting down the parliament.
Because voting "no" wasn't cool or viral enough.

Basically, the treaty originally signed with the Maori in the 1840s has led to that group receiving particular treatment under the government and special favors in the law, while other racial groups don't enjoy those benefits.

Under the proposed legislation, the treaty principles that would be defined in law are:
that the government has a right to govern and that parliament has the full right to make laws
that the rights of Māori are respected by the Crown
that everyone is equal before the law and is entitled to equal protection under it.
