Te Pāti Māori's national council has voted to expel MPs Mariameno Kapa-Kingi and Tākuta Ferris, after a torrid period of internal conflict.
The National Iwi Chairs Forum was hopeful the party's two factions could patch things up at a hui at a Wellington marae this week.
That plan has been scuppered, after the co-leaders announced the party's council - made up of electorate representatives - met last night and voted "without opposition" to expel Kapa-Kingi and Ferris.
In response to news of his expulsion, Te Pāti Māori MP Tākuta Ferris has issued a statement, saying the decision "is plainly unconstitutional" and has called the resolutions 'illegal'
