The former chief executive officer of Pike River Coal has set up a mine safety consulting business.
Peter Whittall was the boss of the West Coast mine when a series of explosions killed 29 men in November 2010.
He is facing 12 Department of Labour charges in relation to the disaster.
Mr Whittall has now registered Peter Whittall & Associates with the Companies Office.
His profile on business networking website LinkedIn says the company consults on technical, safety, commercial and management issues, primarily within the minerals industry.
