Tasman Tanning is to face prosecution over a chemical spill in Wanganui last November which injured 21 of its workers, two of them seriously.
Ministry of Business, Innovation and Employment spokesman Britton Broun yesterday confirmed that the ministry had finished its six-month investigation into the incident and the Wanganui tannery would be in court in June.
Mr Broun could not say what charges the company would face.
"We cannot provide any further information until the matter is called before the Wanganui District Court on June 6," he said.
Tasman Tanning managing director Hunter Tait could not be contacted for comment.
