Police together with the Ministry of Employment, Productivity and Industrial Relations are now investigating how a man died last month after he sustained serious injuries while cleaning the conveyor belt at the Rarawai Sugar Mill.
According to Radio New Zealand, Police say they are working very closely with the Labour Ministry to determine if there were any factors of criminal negligence.
Police also say they have got some remaining reports to come from the engineer.
Meanwhile, there is a separate investigation into how a 24-year-old seasonal worker suffered burns just days after the death of his co-worker.
