The campaign to seek redress for Manahi continued and in 2000, his "iwi", Te Arawa, lodged a claim with the Waitangi Tribunal and was supported in doing so by the New Zealand RSA. Te Arawa alleged the failure of the New Zealand Government to give full consideration of the award of a VC to Manahi constituted a breach of the Treaty of Waitangi, which required the government to act in good faith regarding grievances of Māori. In December 2005 the tribunal reported that there was no breach of the treaty. While not making any formal conclusions or recommendations, the tribunal suggested that the Manahi VC Committee work with the New Zealand Government in making an approach to Buckingham Palace.
