Ngati Whatua and Waikato-Tainui have decided to go to court to challenge the Government's interpretation of "right of first refusal" in light of Budget moves to free up surplus land in Auckland for private housing developments.
But in a bid to avoid souring their relationship with the Government, the tribes are inviting the Crown to join them in seeking clarification of the law.
The tribes have asked the law firm Russell McVeagh to seek an urgent meeting with the Solicitor-General Mike Heron to discuss the possibility of a joint approach to the courts.
The announcement of the joint action follows a meeting yesterday between 13 iwi with interests in and around Auckland and Housing Minister Nick Smith and Treaty Negotiations Minister Chris Finlayson.
