Te Pāti Māori is accusing the police of having double standards when dealing with death threats made against Pakeha and Māori.
The Party has lodged an official complaint to the Independent Police Conduct Authority over the investigation into a video posted online by a white supremacist, threatening to kill Maori and targeting Marae.
Police have received multiple complaints about the video, which was taken down last week.
The Māori Party says the police response has been inadequate as the person responsible was spoken to but not seen as a threat because of mental health problems
Co-leader Rawiri Waititi says in contrast two people have been arrested over threats made to National MP Simeon Brown.
He told political reporter Charlie Dreaver that's not good enough.
In a statement, the police say they acknowledge the concerns raised.
They say the matter is being taken very seriously and officiers have been actively investigating, including searching property.
Because the case is still active, they won't comment further.
