The Pike River families will find out on Tuesday if a body recovery plan has been approved by the Government.
Cabinet voted on Monday on whether to accept a plan drawn up by the mine's new owner Solid Energy after it was approved by the High Hazards Unit, which is in charge of mine safety.
Prime Minister John Key said he wanted to wait until the families of the 29 men who died in the mine had been informed before announcing whether the recovery effort would proceed.

However, he said they would be relieved when they were given an answer in Greymouth on Tuesday.
Mr Key said the Government is committed to funding a plan, provided it is safe, technically feasible and financially credible.
The spokesperson for some of the Pike River families, Bernie Monk, told Morning Report he is confident the Government will give the plan the go-ahead.
He says he is grateful it is putting up the money needed to re-enter the mine.
Mr Monk says the day will be important for anybody wanting answers about what caused the explosion in the mine.
The recovery plan Cabinet considered involves sealing the main ventilation shaft to help stabilise the mine and prevent any further explosions.
A body recovery team would then walk 2.3 km into the main entry tunnel as far as a rockfall caused by the November 2010 explosion.
No plan has been drawn up to move beyond the rockfall, where most of the bodies are thought to be, due to the unstable atmosphere.
Officials from the High Hazards Unit, including the chief mine inspector, will be at Tuesday's meeting in Greymouth but Labour Minister Simon Bridges will not.
The meeting is due to begin at 11am.
