The Waitangi Tribunal released two reports at the end of 2015, on the Ngāpuhi Mandate Inquiry and the final part of its report on the Te Urewera district inquiry.

The sixth and final volume of the Te Urewera Report responds to claims made on behalf of the hapu and iwi of Te Urewera and contains three chapters covering environmental, socio-economic and other issues.

The Ngāpuhi Mandate Inquiry Report is the outcome of an inquiry into 15 claims, primarily from Ngāpuhi hapū and collectives of hapū, relating to the Crown's recognition of the Tūhoronuku Independent Mandated Authority as having a mandate to enter negotiations to settle the historical claims of all Ngāpuhi.
