Remembering the late Richard Nunns' contribution to taonga pūoro

Richard Nunns - the world's foremost expert on the musical instruments of Te Ao Māori, taonga pūoro - has died at 76. He was central to the revival of these traditional instruments. I spoke to Richard's good friend Brian Flintoff - who, with Hirini Melbourne - together collaborated over many years. Brian tells Max Towle about visiting Richard in his final weeks.
