Human remains may have been seen in images taken inside the Pike River Mine, as part of the criminal investigation into the disaster.
Police announced last September they were reopening the borehole drilling operation, with work beginning on 10 additional boreholes in late January.
The police say images show the possible remains near borehole six, where men were believed to be when the mine first exploded.
Advocate Sonya Rockhouse, whose son Ben was killed spoke to Max Towle.
