Today's re-entry to the Pike River mine is expected to provide closure for the families.
An attempt to go into the mine was cancelled at the last minute earlier this month, because of unusual levels of oxygen.
Grey District Mayor Tony Kokshoorn told Kate Hawkesby the Government's brief is to go to the rockfall at the end of a 2.3-kilometre tunnel.
He says 400 metres that hasn't been seen yet by robots or cameras will be covered, but there are probably no bodies in that area.
"But at least from a closure point of view from the families, they can say: 'look we have done all we have and all we can for you, so now you have to accept closure'," he said.
"It will take a little while to get down to the end of the 2.3-kilometre haft but I think at that point we will get some clause fore the families."
