The families of Pike River mine explosion victims are optimistic about police reopening the investigation.
Top police investigators have been in Greymouth recently, and are hoping to get access to the mine's access tunnel or drift. They're not ruling out new criminal charges being laid.

Spokesperson Anna Osborne says people need to be held to account.
"To think that the people who could have stopped this from happening are still out in the community, still living with their families, their children, their wives, their partners, whatever, while we're living with a life sentence."
Ms Osborne says the families of the 29 men killed in 2010 deserve answers.
"For us to get some form of justice for our men and for our families is a huge part in the families' healing."
Pike River families spokesman Bernie Monk will be on The AM Show just after 7am on Monday morning.
