Following nine weeks of hearings between 20 March 2004 and March 2005, the Waitangi Tribunal released the Wairarapa ki Tararua report in June 2010 at Te Oriori Marae, Masterton. Their report covered 28 claims filed by members of Ngāti Kahungunu and the Rangitāne hapū, and other claimant groups. The inquiry district covered the south-eastern corner of the North Island, inland to the Ruahine and Tararua ranges, and northward to Southern Hawke's Bay. The claims investigated by the Waitangi Tribunal, concerning Wairarapa ki Tararua, covered the Crown's purchase of land—including land around Wairarapa Moana—and the compulsory acquisition of Māori land for public works. The grievances of Ngāti Kahungunu included the Crown's forced secession at Mangaroa and acquisition of vast lands throughout their rohe that left Ngāti Kahungunu virtually landless, the loss and degradation of Wairarapa Moana, the Crown's failure to protect Ngāti Kahungunu from the erosion of their tribal structures, and the social deprivation and loss of te reo Māori that followed.
