Bodies remaining in the Pike River Mine are intact and identifiable.

These claims for Anna Osborne, who lost her husband in the 2010 mine explosion.

She said leaked footage, that was handed to the families, reveals the inferno didn't destroy a number of bodies.

After trawling through hours of footage, she said amid un-scorched rubber hoses and pallets are the remains of loved ones.

"Bodies that are fully intact that some ministers would want you to believe that are ash and there's nothing to be retrieved, so we do have images of bodies," she said.

Osborne is making fresh calls for a manned re-entry of the mine.

"I'm sure the Government want the families to go away and convince the rest of the public that there is nothing there to retrieve and we should all just move on. We are not going to walk away, we're going to continue to fight."

Spokesman Bernie Monk said dredging through hours of footage to find it was a huge effort.

"They had to do a lot of work to upgrade the pictures, to make sure that what they were looking at were bodies, and I understand it is," he said.

Monk said the Government needs to heed the families long-standing calls for a manned re-entry now more than ever.

"It's the politicians that are the only ones that are saying the drift's too unsafe to enter. What more do the families have to do to make this happen?"

It follows the release of footage on Sunday showing glasses and paper in tact in the mine's drift.

But Prime Minister Bill English on Monday said there was nothing new about the footage and that it had been been around for years.

He has previously ruled out re-entry, relying on expert advice that it is too risky to go into the potentially explosive methane-filled drift.
