The Crown is offering collective iwi in Auckland a landmark deal under the Treaty of Waitangi which includes 11 volcanic cones in the region.
Sir Douglas Graham, who has been assisting with negotiations, told Morning Report the deal involves collective iwi representatives and the new Auckland super-council managing the volcanic cones on behalf of the people of the region.
He said this is likely to bring an improvement in the preservation of the cones.
As there are many iwi in Auckland, not just Ngati Whatua, Sir Douglas said they are being asked to work together.
He said the group is being offered first right of refusal, to purchase at market value, as with other surplus Crown land.
If the iwi decide to accept the Crown offer, Sir Douglas said an agreement could be signed later in February.
Treaty Negotiations Minister Chris Finlayson says he is optimistic about the offer.
