The Government has topped up Ngai Tahu and Waikato-Tainui's Treaty settlements by $35m to bring them into line with other agreements.
Treaty Negotiations Minister Andrew Little said the payments ensured the value of the two iwi's settlements maintained their relative size compared with all other Treaty settlements.
Ngai Tahu, which settled with the Crown in 1998, received another $18.7m and Waikato Tainui, which settled in 1995, received another $16.6m. That is on top of separate top-ups worth a total of $370 million in 2017.
"This process is about maintaining the agreed relativity between the settlements agreed with Waikato-Tainui and Ngāi Tahu and the total value of all historical Treaty settlements, Little said.
"That was the undertaking made by the Crown in 1995 and 1997 when these settlements were reached, and we must honour it."
