He is known in New Zealand for his work surrounding the revival of Māori culture. A member of Ngā Tamatoa, which petitioned the New Zealand Government to have Maori taught in schools as part of its focus on Maori identity, he also studied at Auckland University and later became the Dean and associate professor of Māori and Pacific development. Melbourne is a significant figure in the revival of the Maori language with dozens of his now classic songs sung in classrooms throughout New Zealand. The power of his melodies and the brilliance of his compositions have still to be widely recognised beyond the classroom however. In the last two decades of his life Hirini’s musical interests extended to a fascination with traditional Maori instruments. Initially intrigued by instruments found only in museum glass cases, he subsequently met ethnomusicologist and performer Richard Nunns and from 1989 onwards the two regularly performed together on marae, and in schools, galleries and concerts. This partnership lead to the release of ‘Te Ku Te Whe’, a CD of original and traditional compositions for a variety of Maori flutes which has been awarded a Gold Disc Award. A second CD together with a DVD ‘Te Hekenga-a-rangi’ was released in 2003. In 2002 Hirini was awarded an Honorary Doctorate from the University of Waikato where he had been a lecturer in the Department of Maori. He was made an Officer of the New Zealand Order of Merit in the 2003 New Year’s Honours just before his death a week later.
