The advert says it is looking for an electrical technician who "puts safety first" and is able to quickly build strong working relationships based on trust and transparency.
The role requires a person with underground experience, qualifications and a full NZ Electrical Licence (EWRB), preferably with a Mining Endorsement.
Ray Crocker, a manager at Beyond Recruitment specialising in engineering and technical roles, said someone with those qualifications was rarer than hen's teeth.
"My guess is they will have to pull someone from Australia," he said.
Crocker said the underground experience requirement made it a very specialised position.
"They will probably want a degree qualified person," he added.
He expected the role, which is a fixed term contract until October, to attract a salary of close to $200k.
The job advert went out on Monday with the position closing on January 25.
Crocker said it was a pretty short window for the kind of person they were looking for.
"They probably should have put the ad out prior to Christmas."
The agency said it would also be advertising two further mine positions in the coming weeks.
The government has allocated $36 million for the re-entry and work is expected to start on it by February with the first major task breaching the 30m seal inside the drift.
