The Pike River Recovery Agency is advertising for five mining staff to assist with the re-entry and recovery of the Pike River drift.
Yesterday Pike River Minister Andrew Little, told Checkpoint the mine would be treated as a crime scene if and when re-entry occurred.
The remains of 29 miners have been trapped in the mine since it exploded in 2010.
Pike River Recovery Agency chief operating officer Kevin 'Dinghy' Pattinson told Checkpoint the new miners would carry out preliminary work initially before the re-entry.
"We need five people - experienced mine workers and by that I mean two to five years' underground mining experience at least," he said.
The miners would eventually re-enter the mine once approval was gained from the minister later on in the year, Mr Pattinson said.
He said the preliminary work would mainly consist of laying out pipelines to the nitrogen plant - which is due to arrive on 1 October - as well as other pipelines to the boreholes, and installation of emergency doors on the mine entrance.
Mr Pattinson said he was part of the team that went in the mine in 2011.
Different pieces of footage from inside the Pike River Mine were reported on last year, one of which was said to show unburnt material inside.
Sonya Rockhouse, whose son Ben died in the mine, last year said the police had handed over footage from inside the mine to her.
At the time, Ms Rockhouse said one of the clearer images showed an intact body, and there were other pictures showing bodies in other parts of the mine.
However, Mr Pattinson said he was not sure what they would find once they re-entered.
"[Our] mandate is to only cover the drift up to the rockfall ... We don't know what we'll find in the drift," he said.
"There's round about probably 600m up to the rockfall that hasn't been explored at all and we don't know we'll find there. But we'll bringing any equipment out in those areas.
"We'll be prepared for whatever we find."
In July, Mr Little signed off on plans which outlined three re-entry options, for which further development was underway.
Mr Pattinson said they would be assessing the risk on those options, and by the end of October will make a recommendation on whether it was safe to re-enter and which option they would want to take.
"Our process we're following will determine whether it's safe or not," he said.
"To date, all the planning work we've done with the technical experts hasn't highlighted any showstoppers that would say it's unsafe, bearing in mind we have still got to put our plan through before risk assessment."
He said if all went to plan, they could be breaching the seal - the 30m wall - by the end of the year or beginning of next year.
