The Tuhoe chief negotiator says the iwi may have to consider abandoning Treaty talks with the Government after it decided not to return Te Urewera National Park.
Tamati Kruger says the Prime Minister's personal veto on the issue of confiscated land has humiliated those involved in the settlement process and embarrassed the Cabinet.
Mr Kruger says the return of the confiscated land has always been Tuhoe's bottom line in negotiations, and the correct forum for a fair hearing may end up being the United Nations.
He says that, after two years of talks, he wants to know whether agreements can be preserved or whether the only option is to involve a third party.
