The widow of a man killed in a West Coast mining accident hopes an inquest into his death will reveal the dangerous working conditions in New Zealand mines.
Robert McGowan, 39, drowned in a flash flood in the Tiller Mine in 2006.
Mine manager Gary Haddow and a consultant geologist, who has name suppression, were found guilty of failing to ensure Mr McGowan's safety and ordered to pay reparation.
However, the geologist appealed and the charges against him were withdrawn at a hearing this week.
Valma McGowan said she is disgusted by the decision and warns there will be more fatalities, as she believes mine safety has not improved since her husband's death.
Mr McGowan's inquest will be held later this year.
