The sole survivor of the Anzac Day 2010 military helicopter crash today launched his court bid to seek criminal prosecutions for his air force superiors.
Sergeant Stevin Creeggan had been travelling with three other members of the Defence Force in an Air Force Iroquois when it crashed in bad weather above Pukerua Bay north of Wellington in 2010.
Flying Officer Daniel Gregory, Flight Lieutenant Hayden Madsen and Corporal Ben Carson died in the crash.
Sergeant Creeggan, who suffered serious injuries, was found 25 metres away from the wreckage.
Details of today's proceedings at the Wellington District Court were suppressed due to sensitive medical information.
