Last Friday, Sergeant Creeggan won a guilty plea from the New Zealand Defence Force in the Wellington District Court after taking a private prosecution against his own commanders. The prosecution followed a successful application for leave to file charges outside the usual timeframe.
It was said in court to be the first private prosecution carried out under health and safety legislation amended a decade ago to allow individuals to take such cases.
So much time has passed between the crash and the verdict that the Department of Labour has gone through two incarnations - it was folded into the Ministry of Business, Innovation and Employment and then became WorkSafe NZ.
The agency's high hazards and specialist services manager Brett Murray said an "offer of a contribution towards Mr Creeggan's costs" had been made. He said it was "recognition of the Department of Labour's role in this incident".
He said it had been publicly acknowledged there had been an "error in not investigating the crash because [the department] mistakenly believed it fell under another agency's jurisdiction".
"The department had no ability to launch a prosecution once the error had been realised as, firstly, it had no evidence as there had been no investigation, and secondly, even if it had evidence, it is required to prosecute within six months of first becoming aware of the incident."
Mr Creeggan paid tribute to solicitor Charles McGuinness of Cullen Law and prosecutor Tim Mackenzie of Wynn Williams for pursuing the case with minimal fees.
