Wellington is playing host to one of the city's most important arts events this year - the contemporary indigenous arts festival Kia Mau. It's grown from its enthusiastic but smaller-scale beginnings eight years ago to an extraordinary collection of indigenous talent from all round the Pacific Rim. Aotearoa New Zealand, of course, but also Samoa, Tonga, Malaysia, Cambodia, Canada - even Africa. Simon Morris is joined by the founders of the Kia Mau Festival - two of this country's most distinguished and talented creatives - playwright Hone Kouka, and poet, producer and film-maker Miria George.
