Kaikōura signed the Herald (Bunbury) sheet of the Treaty of Waitangi at Tūhawaiki’s request on 10 June 1840 on board HMS Herald, which was anchored off Ruapuke Island. In 1990, Wharetutu Stirling gave evidence at a hearing of the the South Island Māori Appellate Court that this was Kaikōura Whakatau, the Ngāi Tahu rangatira of Kaikōura. [1]
