Systematic health and safety failures stretching into the upper reaches of the Department of Labour were among the causes of a deadly explosion in the Pike River mine, an expert has claimed.
Auckland University human factors expert Kathleen Callaghan criticised the department's proceedures in evidence to the Royal Commission of Inquiry into the Pike River mine disaster today.
She said many of the health and safety problems at Pike River mine that led to the November 19 mine explosion which killed 29 men were also present in the DoL.
A DoL commissioned reported which largely exonerated the department for its role in the disaster, called Gunningham and Neal, was often wrong, she said.
"The error producing conditions at Pike River mine are not dissimilar from the ones that are identified at the Department of Labour. They are very very similar and I think we need to be mindful of that... There is evidence to show a causal link with the regulator.
