The Maori Party say it's not fazed by criticism by Tai Tokerau MP Hone Harawira which the caucus says is just 'Hone being Hone'.
The Mana Party leader says his former caucus has abandoned people in his electorate and its leaders do what they want, not what the people want.
Mr Harawira says the Maori Party's latest Tai Tokerau candidate, Te Waihoroi Shortland, should watch his party otherwise he could end up like him or Solomon Tipene, no longer with the party.
Mr Tipene stood in the June by-election for Te Tai Tokerau and came third in the polls.
The Maori Party says it did not turn its back on Mr Tipene and that it is unfortunate he did not get the backing of the voters.
Co-vice president Te Orohi Paul says Mr Harawira has his view, but that is not the Maori Party's focus.
She says its focus is on supporting Te Waihoroi Shortland, who aims to achieve the goals of his iwi.
