Te Iwi Moriori say they are happy to co-manage resources on the Chatham Islands - so long as their Treaty claims are acknowledged differently from Ngati Mutunga, the other tribe on the islands.
Treaty Negotiations Minister Christopher Finlayson visited the islands last week and spoke to Moriori.
Hokotehi Moriori Trust executive chair Shirley King says Mr Finlayson is keen to reach a settlement with them, but there are a few overlapping areas that need to be ironed out.
Moriori claims are different from those for which Ngati Mutunga o Whare Kauri is asking.
Ms King says when the Maori Land Court claimed all of the land less than 3% was given back to Moriori.
When the Foreshore and Seabed Act took effect it created a barrier to their claims.
Ms King says Moriori have made a decision to co-operate with Ngati Mutunga over most of the island, but Te Whanga Lagoon is one area to which they want customary title.
Moriori are yet to get a mandate to enter into Treaty negotiations with the Crown.
