Best of the Week - 17 April 2015

This week..... the ethics of spying within New Zealand, the much-hyped launch of the new Paul Henry news show, The Family of Twelve - a group of New Zealand wineries working together, a blind runner and her world champion running guide take on the London marathon, studies into the active volcanic field Auckland is built on, a native forest trust celebrates the release of its 200th reared Kiwi chick, crackers made from spent grains used in beer making, and making it rain on stage for the musical Singin' in the Rain.
