"If Ngati Kahu have not concluded a treaty settlement within three years of Ngai Takoto settlement date, around December 2018, then Ngai Takoto will have the sole right to purchase the property," Mr Finlayson said during debate on four northern settlements: Ngati Kuri, Te Aupouri, Ngai Takoto and Te Rarawa.
"This approach was taken because the Crown had to balance the interests of both iwi while ensuring certainty about the future of the airport."
Ngati Kahu had not been locked out negotiations, he said, and he hoped Ngati Kahu would get involved in negotiations soon.
He hoped Ngati Kahu were not going to be criticised for occupying the airport, Mr Finlayson said.
"It's not. There are a few miscreants who are doing it. They don't reflect Ngati Kahu. I hope that the day will come very soon when the miscreants will get lost and Ngati Kahu negotiators, be they the current ones or new ones, will sit down with the Crown and sort out these arrangements.
"There is no place for this kind of oafish behaviour, and I say no more than that because it is a matter for the police. It is an operational matter and politicians don't get involved in operational matters."
Both Ngai Takoto and Ngati Kahu would be involved in the renegotiating lease arrangements for the airport with Far North Holdings Ltd, the commercial arm of the Far North District Council.
