Iwikau signed the Herald (Bunbury) sheet of the Treaty of Waitangi at Akaroa on 30 May 1840. He was a rangatira (chief) of Ngāti Rangiāmoa, the senior line of the Ngāi Tuahuriri section of the Ngāi Tahu iwi (tribe). He was a half-brother of Te Maiharanui, who in 1830 was captured by Te Rauparaha on the Elizabeth and killed. His other siblings were Mukoko, Parekaiakaaka and Maikoukou (this may be an alternative spelling of Mukoko). Their parents were Te Whe and Haritaua. He married Wahaka, the fifth child of Tutuke and Te Wakarawa. [1] Iwikau had a daughter who married the whaler James Robinson Clough, also known as Jimmy Robinson or Rapahina. They had a child named Abner. [2]

Iwikau was the main rangatira of 450 people living at Koukourarata (Port Levy) on Banks Peninsula. [3] He was described as ‘a person of agreeable and gentlemanly manners’. [4]

In 1834, Iwikau was a leader in the Ngāi Tahu campaign to the Marlborough Sounds known as Oraumoa nui or Taua nui. Ngāi Tahu brought 500 fighting men and stayed for two months, but Ngāti Toa kept out of sight. [5]

Robinson Clough did not marry the daughter of Iwikau. That was a story probably started by Robinson and published by HC Jacobson in Tales of Banks Peninsula. His chapter on Clough contains many errors. Clough lived for a few years with Puai, daughter of Tuhaewa and Riteka of ngati irakehu.
