Sir Ian Hugh Kāwharu ONZ (born Ian Hugh Paora; 18 February 1927 – 19 September 2006) was an academic and paramount chief of the Ngāti Whātua Māori tribe in New Zealand.
Hugh was born to parents Janet and Wiremu Paora in Ashburton, New Zealand in 1927 and christened Ian Hugh Paora. While a child, his surname was changed from Paora to Kāwharu, in remembrance of his great-grandfather Paora Kawharu (Hugh's grandfather had the patronym Hauraki Paora). Kāwharu attended Auckland Grammar School. He gained a BSc in geology and physics from the University of Auckland, an MA in anthropology from Cambridge University and an MLitt and DPhil from Oxford University.
In 1970 he became the foundation professor of social anthropology and Māori Studies at Massey University. Between 1985 and 1993 he was professor of Māori Studies and head of the Department of Anthropology at The University of Auckland, where he directed the building of the university's marae and was made an emeritus professor after he retired.
He was chair of the Ngāti Whātua o Ōrākei Māori Trust Board from 1978 to 2006. He served on the Royal Commission of the Courts (1976–1978), the New Zealand Māori Council, the Board of Māori Affairs (1987–1990) and the Waitangi Tribunal (1986–1996). He was a New Zealand delegate to UNESCO and a consultant to the United Nations Economic and Social Council (ECOSOC) and the Food and Agriculture Organization (FAO). He was also President of the Polynesian Society.
