Last year, after Rangitāne Tū Mai Rā Trust board took an urgent application to the Waitangi Tribunal—it was asked to review the Crown's actions in failing to engage with Rangitāne regarding the additional redress of Wairarapa Moana in the Ruamāhanga River, and alleged breaches of its commitments to Rangitāne in its deed of settlement. The Waitangi Tribunal found that the Crown had failed in its Treaty duty of good faith to Rangitāne. It did not continue to negotiate with them about Wairarapa Moana in good faith, as required by clause 7.6 of the Rangitāne deed of settlement, and it breached the principle of whanaungatanga, knowing the nature of the engagement and relationship between the two groups in the past, and the Crown's historical errors putting Rangitāne interests under those of Ngāti Kahungunu. The Crown should have taken active steps to ensure that the relationship between them was not harmed by its approach to shared or joint redress.
