The Race Relations Commissioner says Hone Harawira may not have broken the Human Rights Act in his racially charged email.
The Te Tai Tokerau MP is fronting up to Maori Party officials today to discuss the language he used defending his trip to Paris.
Commissioner Joris de Bres says unlike students wearing Nazi uniforms or schoolboys bowing to a swastika Mr Harawira's comments are not a breach of the Human Rights Act, because he is entitled to freedom of expression.
But he says the issue should be addressed.
"It is something that the organisation that they represent or that they are a part of has a responsibility to address so in this case, it is important that the Maori Party upholds its values and its standards."
Mr De-Bres says as a member of Parliament, Mr Harawira is expected to uphold high standards in the public arena.
More than 20 complaints have been made with the Race Relations Commission about the email and Mr de Bres says each one will be looked at individually.
