Best of the Week - 15 April 2016

Highlights from RNZ National's programmes for the week ending Friday 15 April. This week.....it was the biggest ever leak of newsworthy information and the biggest collaboration between media organisations - but the New Zealand media were out of the loop on the publication of the Panama Papers, a former Waikato dairy farmer who operates the biggest legal cannabis operation in the US, is surgery the ultimate placebo? A young Muslim black woman is representing New Zealand at a commonwealth leaders programme, walking better could stave off knee surgery, a book on the history of New Zealand women, playwright Roger Hall on his life and influences, chart topping musician Tiki Taane recreates his one man show live , bull semen for hair care products, and celebrating mangrove forests.
