The Pike River Recovery Agency is expected to hand over its final re-entry plan to the Government today.
The agency's been working alongside experts to establish the safest way into the tunnel of the West Coast mine.
The aim is to find remains of the 29 men who lost their lives eight years ago in the explosion, and to search for clues as to why it exploded.
The experts have come up with three plans for re-entry, which the agency has been reviewing for two weeks now in preparation for its final Government recommendation.
CEO Dave Gawn said earlier this month that he would not take a plan to Pike Recovery Minister Andrew Little unless he was confident they were "in a space to make a recommendation of a course of action that is both technically feasible and safe to undertake".
He said there was "still a lot of stuff that we don't know", such as the condition of the drift.
"But we know we can get inside safely."
Anna Osborne of the Pike River Families Reference Group told 1 NEWS' John Campbell earlier this month that the re-entry is "real now".
"It's happening, this is happening," she said. "We've fought so long we've had so many road blocks put up in our way, but no, not anymore."
