Ngapuhi leader David Rankin has called for the University of Auckland to dismiss prominent Maori academic Professor Margaret Mutu, labelling her the "Robert Mugabe of New Zealand politics".
Mr Rankin made the comment after Professor Mutu said there should be a cap on the number of white people migrating to New Zealand.
Her comments in the Sunday Star Times said the number of people coming from South Africa, England and the United States should be restricted, as they bring attitudes of white supremacy and are destructive to Maori.
Mr Rankin described the comments as "racist".
"Margaret has gone too far this time," he said.
