Pike River mine families still fighting

Some Pike River mine families are still fighting for a corporate manslaughter law 15 years after the diaster that killed 29 men. The deaths lead to the creation of WorkSafe and the 2015 Health and Safety at Work Act, which passed with cross-party support. A Royal Commission of Inquiry found New Zealand's old safety laws lacked the teeth, and there were catastrophic failings in the mine company's systems, despite numerous warnings of a potential catastrophe. Now the government is changing the Health and Safety at Work Act to quote "cut through unnecessary red tape" holding businesses back. Nigel Hampton KC spoke to Lisa Owen.
