Te Kapunga Matemoana "Koro" Dewes (7 April 1930 – 17 August 2010) was a kaumātua of the Ngāti Porou iwi of New Zealand.
Dewes attended Horoera Native Primary School and won a scholarship to Wesley College, where he became dux and head prefect.
[1] At Wellington, he helped to extend courses to allow students to complete a degree major in Māori language.
He wrote a master's thesis on the work of composer Henare Waitoa, which was submitted in Māori in 1972.
[5][6] Māori Affairs Minister Pita Sharples said Dewes "was a partisan rather than a diplomat" who "has been an inspiration for language activists from every iwi, and for indigenous peoples around the world.
