The lawyer for the Pike River families says the possibility that two bodies might have been found reinforces the need to enter the mine.
Twenty-nine men died in a series of explosions that began at the West Coast mine on 19 November, but no one has been able to go into the mine and no bodies have been recovered.
Images of what could be two bodies have been shown to the families for the first time this week.
The pictures will undergo an electronic enhancement process in the next three months.
Lawyer Colin Smith, who has seen the images, says there's substantial evidence to be gained from entering the mine.
Without that, he says, conclusive knowledge about what occurred cannot be gathered for the Royal Commission of Inquiry into the disaster.
