The country's top military leader has publicly apologised to the family of an airman killed when an old artillery round unexpectedly exploded last year, saying not enough was done to explain the findings of a court of inquiry into his death.
Air force explosives expert Flight Sergeant Andrew Bruce Forster died at the Waiouru Military Camp last November when he was hammering a marker stake into the ground about half a metre from a rusty and unexploded 105mm Howitzer shell.
The shell exploded and he died instantly. Another sergeant who was standing close by escaped with minor injuries
The court of inquiry ruled that what caused the shell to explode may never be known.
However, it found F/S Forster failed to follow several standard procedures which may not necessarily have caused the accident but exposed personnel and equipment to avoidable risk.
