Opposition parties are calling for the Maori Party to walk away from its deal with National.
The Maori Party wants iwi to keep pressure on the Government over the inclusion of Treaty provisions in new legislation paving the way for partial asset sales.
And it has called for iwi leaders to test treaty clauses in the current law, by taking their cases to court.
Labour says if the Treaty is fundamental to the Maori Party, then it can't see how they can ask others to fight, but remain in a governing arrangement.
The Mana Party says if the Maori Party wants to be seen to be leading, it must walk away from National.
