A scanner is due to be lowered into a bore hole at the Pike River mine on Thursday, to assess conditions inside the mine in which 29 men were killed in explosions last November.
Receiver John Fisk of PricewaterhouseCoopers says efforts were made on Wednesday to lower the scanner into the mine, but more work was needed to the drill hole used to access the mine.
Mr Fisk says the scan will proceed on Thursday and it is hoped it will reveal the state of the West Coast mine, how much of it can be salvaged, and clarify the chances of recovering bodies.
He says it will take some time for the pictures to be processed and analysed, and information will be shared first with the men's families.
