A relativity clause in Ngāi Tahu and Tainui's Treaty settlements means the government is likely to make further big payments to them as more iwi settle their claims. It was revealed yesterday the government paid an additional $370 million dollars to the two iwi late last year under the terms of their 1990s settlements. Tainui received an extra $190m and Ngāi Tahu $180m. The clause was included to ensure the settlements remain in proportion to later agreements. Minister for Treaty Negotiations Andrew Little tells Guyon Espiner he made the call "not to bury the announcement before Christmas".
