The report of the Royal Commission on the Pike River mine disaster and the Government's response will be presented to the families of the victims in Greymouth on Monday.
Twenty-nine men died in a series of explosions at the West Coast mine that began on 19 November 2010.
Government ministers Gerry Brownlee and Chris Finlayson will present the report in a private meeting before releasing it publicly.
Mr Finlayson says the report is the result of a very wide-ranging and comprehensive inquiry.
He says it examines what happened in the mine, important policy questions around the mining industry and makes recommendations as to how to avoid this kind of tragedy occurring again.
Mr Finlayson says it is an important milestone for the families and it is essential they are able to see the results of the investigation which they have patiently observed and taken part in.
