Politics Friday: Tracey McClellan and Gerry Brownlee discuss cancelled events, Pike River and Groundswell - Canterbury Mornings with John MacDonald

Today on Politics Friday, John MacDonald was joined by Labour's Tracey McClellan and National's Gerry Brownlee.
Topics for discussion included the recent cancellations of events in Canterbury, and if Government's new Traffic Light System provided enough clarity for organisers. 
They reflected on the Pike River tragedy 11 years, and discussed whether investigations should continue if they were to result in charges being laid. 
The Groundswell protests will go ahead in parts of New Zealand on Sunday. McClellan and Brownlee reacted to the protests, and the comments made by Stuart Nash in Parliament yesterday.
