The Government says it believes Treaty settlements of historical claims will be durable.
More than 60 packages have been completed, including Tuhoe's earlier this week.
The Minister for Treaty of Waitangi Negotiations, Chris Finlayson, says he's very confident about the durability of settlements, and that New Zealanders have great generosity of spirit.
Mr Finlayson says he's often asked if the claims will be revisited in another 40 years, but he says answer is they won't.
Over the past few years, the pace of Treaty settlements has been rapid.
The National-led Government has pushed through more than 30 packages in four years. Labour's record was 15 over 9 years.
Treaty lawyer Willie Te Aho says although the settlements are moving speedily, quality is not being sacrificed.
He says iwi have a choice to either negotiate directly with the Crown, or go through the Waitangi Tribunal first.
Mr Te Aho says there's no rush, and tribes need to select which process suits them.
