The spokesperson for some of the families of Pike River mine victims says he is confident the Royal Commission's report on the tragedy will reveal the truth.
Twenty-nine men died in a series of explosions at the West Coast coal mine that began on 19 November 2010.
The report of the Royal Commission, headed by Justice Graham Panckhurst, will be presented to the men's families in Greymouth on Monday and released later in the day.
"I've got the utmost confidence in the three people that were running this commission headed by Mr Panckhurst'" family spokesman Bernie Monk told TV3's The Nation programme on Saturday.
"I've got every confidence that they're going to come out with what the country needs to hear."
Nigel Hampton QC, who represented the Engineering Printing and Manufacturing Union before the Royal Commission, hopes the report will recommend changes that will improve the safety of the coal mining industry.
"I think there are systemic problems about health and safety throughout the country, not just in the high hazard industries, and I think this may mark a watershed in terms of health and safety legislation generally," he told TV3.
Mr Hampton hopes the report will also call for a better funded inspectorate of mines.
