Stuff The wreckage of an Air Force Iroquois which crashed at Pukerua Bay, north of Wellington, on Anzac Day, 2010. WorkSafe was so concerned about a spate of deaths and injuries in the military that it met three times with the Defence Force last year to discuss ways of improving health and safety. National Correspondent Tony Wall reports. Karl Maddaford made it clear in emails he sent to staff in the safety directorate at the New Zealand Defence Force (NZDF) that he was a “straight talker” employed by WorkSafe to “get results”. Last July, Maddaford had just been appointed to a new role as national manager of critical response, in charge of building WorkSafe’s ability to respond to civil defence and emergency management events, and provide specialist support for investigations.
