Kahu Karaitiana was born beside the Cam River in North Canterbury, the son of Wiremu Ihakara Karaitiana and Ruiha Titapu Taituha. His father’s tribe was Ngāti Kahungunu of Heretaunga and Wairarapa and his mother belonged to the paramount hapu Te Rangiamoa of Ngaitahu. Karaitiana was educated at Tuahiwi School and Hikurangi College at Carterton. He won the 40-mile cycling competition in the 1934 Canterbury Championships. Karaitiana was an ardent student of Māori history, mythology and genealogy, having been taught by his father who was the compiler of the historical records of Ngaitahu at that time. Karaitiana married Violet Coulthurst in Auckland in 1939 and had three sons. They moved south to Christchurch where he worked as a carpenter and he also carved for pleasure. He sang on stage and radio and travelled to the Far East as a tenor with the Katherine Dunham Show in 1957. Karaitiana was a tenor with Porgy and Bess Opera which featured the late Inia Te Wiata and was performed throughout Australia. He was a member of the Three Tuis with Martin Winiata and Monty Graham; they sang on Radio 3ZB and gave concerts in the Civic Theatre in Christchurch. Karaitiana wrote a number of stories but only two were published. One of his stories was included in a Japanese publication. He died 26th June 1979 aged 69 years.
