The remains of up to three more Pike River miners have been located during a police operation to gather video evidence via boreholes deep into the mine.
29 men were killed in the explosion in November 2010. Police announced in September last year they were reopening the borehole drilling operation as part of the criminal investigation into the explosion.
The latest discovery means up to 12 of the 29 miners have been located.
And the boreholes have now been resealed. Detective Superintendent Darryl Sweeney explains where the investigation is at.
