Explosions at the West Coast underground coal mine in November 2010 killed 29 men, and seven years later a plan is being formulated to recover their bodies.
Thirty one experts have been meeting just outside Greymouth for the past three days trying to nut out how a manned re-entry of the 2.3 kilometre long entry tunnel could be done safely.
They include a who's who of the mining sector covering geotechnical engineering, mine ventilation and health and safety.
A spokesperson for the agency set up to oversee the effort, the Pike River Recovery Agency, said a final plan would be presented to the minister in charge, Andrew Little, in June or July.
