A multimillion-dollar trust is being planned to continue efforts to recover workers' remains from the Pike River mine, and the taxpayer is being asked to contribute.
Work is continuing at the mine to reach the remains of the 29 workers who died in explosions 14 months ago - which some families say they need to move on.
However, as receivers PricewaterhouseCoopers prepare to sell the mine to new owners in the coming months, there is uncertainty over who will pay for any ongoing recovery efforts.
The receivers have money set aside only for reclaiming 2.3km of the tunnel up to a rockfall blocking off the rest of the mine.
A meeting in the next few weeks between Grey Mayor Tony Kokshoorn - who is promoting the trust idea - Prime Minister John Key and the receivers is expected to explore how it could be put together and funded.
