The Spring Creek underground coal mine on the West Coast has reopened after it was shut down on Wednesday when a miner was nearly killed by falling coal.
The Ministry of Business, Innovation and Employment's high hazard unit issued a notice to shut down operations at the mine, near Greymouth, following the accident.
The ministry earlier said it had concerns about seam stability in the mine, and said the accident had the potential to be fatal.
The mine's owner, Solid Energy, said in a statement that this notice has now been lifted.
A new underground area is being developed at the mine and the installation of infrastructure needed to mine and transport coal from the new block is the current focus of mine operations.
The miner's condition yesterday was "fairly comfortable", according to a Christchurch Hospital spokesperson.
Spring Creek is near the Pike River underground coal mine where 29 workers died in 2010 and was shut for six months after that mining disaster. There was another closure for three days in February.
Spring Creek was initially developed in 2002 and employs 230 people.
