Te Pati Maori says the Prime Minister has no right to police their language

Chris Luxon's spoken to his Deputy Winston Peters, over likening co-governance to Nazi Germany.

He's also urged all leaders to avoid inflammatory remarks -- saying Te Pati Maori this year accused the Government of behaving like white supremacists.

Co-leader Debbie Ngarewa-Packer says unless Luxon's experienced racism as a Maori, he can't tell Maori how they should be speaking out about it.
