There appears to be no end in sight over the ongoing dispute between the Pike River families about the future direction of the mine's recovery.
A number of families said they were blindsided by that.
The Pike River Family Committee, which is separate to the reference group, met last night and say three-quarters of the families want to self-fund a feasibility study into recovering the mine's main ventilation fan.
But the level of support for the study is also in dispute.
Last week's statement by the Pike River Family Reference Group - which is the official group working with the government's mine recovery agency - sparked uproar among some relatives of the 29 dead miners.
The reference group represents 27 of the families.
It said the families accepted advice from Pike River Re-entry Minister Andrew Little that there would be no more money to expand the project.
Bernie Monk lost his son in the disaster. He is not on the reference group and has rejected the minister's claim.
He told Checkpoint that 23 of the 29 families support a feasibility study on going further inside the mine, while two want the mine to be re-sealed.
"We started last night. As soon as I finished the meeting and Carol Rose (who lost her son at Pike River) and one of our experts which is Richard Healey (an electrical engineer) and our family, we went home. We did a call to the UK and Tony Foster answered it who was on the meeting last night - one of our experts - he got in touch with our man (another expert).
"He'd already been in touch with him before I rung him. That's how quick we've started on this."
The study will be be done free of charge by independent mine experts and will look into the costs of recovering the mine's main ventilation fan, identifying risk factors, and present them to the government.
Some families believe the fan may hold vital clues to what caused the disaster.
Monk said last week's statement by the reference group should not have been released.
"So they made decisions on behalf of the families because they thought that they had the complete mandate to make these decisions without going to them and asking them to vote on it and they made these decisions without the vote."
Anna Osborne from the families' group was standing by last week's statement.
"No regrets at all at releasing it to the media because what it was was actually putting our truth out there to say we understand that it's just too hard. It will cost too much money to get further.
"It's not as simple as what some family members think or want other family members to believe."
According to her, the lack of support for it was because not everyone replied to emails or attended meetings.
Osborne, whose husband died in the explosion, tuned into last night's meeting and disputed the committee's claim that 23 families supported plans for a feasibility study.
"I don't understand how they say they have the support of 23 families when I know only about 13 families turned up for the meeting."
Monk said Osborne was incorrect.
Meanwhile, the minister said going beyond the mine's roof fall was a huge undertaking, and there are other ways to look into the mine workings.
"Police have agreed to drill six extra bore holes and to send down scanners to try to retrieve exactly the evidence which some families are saying could be achieved by physically getting there," Little said.
The Pike River families hope their own feasibility study will be complete in the coming weeks.
