RNZAF deaths in WWII were 4149, and the official history "New Zealanders in the RAF" Volume II page 9 says that there were just under 11,000 New Zealanders with the RAF of whom 3290 or nearly one third lost their lives. See the history online: http://www.nzetc.org/tm/scholarly/tei-WH2-2RAF.html The Empire Air Training Scheme was for training Aircrew not ground staff, so were likely to have a high casualty rate. There were also a number of New Zealanders flying with the Fleet Air Arm (FAA). Yours, John Wilson
