Mr Little said this morning he did not necessarily support self-governance by Maori but it was important to find out what Ngapuhi wanted and how it would work in practice.
He cited examples such as the co-governance of the Waikato River and Waikaremoana.
"It's not about abandoning what we've got now, it's not about abandoning the fully-functioning democratic country we've got. It's about doing what we've always done under the Treaty. That is rising to the occasion, sitting down and talking and coming up with sensible solutions."
Mr Key described Mr Little's initial suggestions as "separatist." He dismissed suggestions that National had effectively given Tuhoe some self-governance in the provisions of the Tuhoe settlement, which included increasing Tuhoe control over Te Urewera park. Mr Key said that amounted to shared governance rather than self-governance.
Mr Little said Mr Key was "playing a political game" by talking about separatism. He said Mr Key was showing weak leadership by simply dismissing the Waitangi Tribunal report.
"You can't just ignore things under the Treaty."
