It seems ever more likely a team will head into the Pike River Mine after experts found no "showstopping" obstacles preventing re-entry.
Twenty-nine men were killed and trapped in the mine when it was rocked by a methane blast on November 19, 2010 but so far expert teams have been unable to reach the bodies of the men.
However, the Pike River Recovery Agency appointed by the Labour-led Government to examine the risks of re-entering the mine, says it has so far turned up no "showstoppers".
"[The team of experts have] been poring over the ins-and-outs of each task required to enable re-entry via the three agreed options," agency chief executive Dave Gawn said.
"There's still a couple of stages to go before the agency pulls together its recommendation to the Minister, but I'm confident that at this stage, there's nothing I've heard that would mean re-entry is impossible."
