A group opposing the Government's bid to rush through a historical Northland Treaty claim could seek an urgent hearing before the Waitangi Tribunal.
Last week the Government accepted the Ngapuhi tribal body, Tuhoronuku, as Ngapuhi's official negotiator.
On Monday night an alliance of Ngapuhi hapu - or sub-tribes - discussed seeking a judicial review or an emergency hearing before the Waitangi Tribunal.
Pita Tipene of the alliance says they're also considering whether Tuhoronuku chairman Sonny Tau or Treaty Negotiations Minister Chris Finlayson may have deceived and manipulated the people during the negotiations.
He told Morning Report Ngati Hine members are willing to try anything they can to change the decision.
"People are really up in arms over this and they are looking at any way to stop Tuhoronuku because we know people don't support it."
He says 63 percent of the submissions on the mandate opposed it because some hapu do not trust the runanga.
Mr Tipene says the National Party has talked about settling all claims by the end of 2014 but rushing through a settlement will only create a new grievance.
Mr Tau is rejecting allegations he has misled the Crown, saying the figures speak for themselves.
He says 76.4 percent of Ngapuhi support Tuhoronuku's position and "we're not going to play political ping pong with individuals who don't have a constituency."
