In May 1995 the Crown signed a Deed of Settlement with Waikato-Tainui that included cash and land valued at $170 million (since topped up with an additional $260 million, with more to come). The public was told at the time the settlement was "full and final". However, full and final it does not appear to be as the iwi moves beyond negotiating for economic benefits to pushing for statutory power through co-governance arrangements, seats at the council table, and the RMA.
In 2010 a deal was struck with Waikato-Tainui for the co-governance of the Waikato River. But wait, there’s more - recently the tribe announced it is now pushing for their next stage of Treaty settlements, which includes seeking co-governance of the Kawhia, Aotea, Whaingaroa and Manukau Harbours, and ‘subsidiary interests in Auckland region’, see Waatea news item – ‘Tribe ready for Harbours claim’ here.
Waikato-Tainui is not the only tribe seeking to further statutory powers via Treaty settlements. This is happening in other areas of the country as well. The number of Joint Management Agreements has grown enormously over the last decade.
