Bernie Monk on next step for entry to Pike River mine

It's been a long wait for the families of the 29 men killed when Pike River Mine exploded in 2010. But work is now underway to prepare for the next step in the process -- that is recovery workers breaching the second seal 170 metres into the mine drift and going where no-one has gone since 2011. Last week, work began to remove the remnants of the first barrier - 30 metres into the drift - and to take out infrastructure used to take water away from the mine. Timothy Brown visited the mine yesterday to see how work is progressing, and afterwards caught up with Bernie Monk - whose son Michael died in the explosion.
