Cox said according to Royal New Zealand Air Force statistics, during WWII 13,235 New Zealanders trained as aircrew - pilots, navigators, flight engineers, wireless operators, air gunners, and bomb aimers.
Half of the pilots trained in New Zealand and half in Canada, after doing their initial flying training in Tiger Moths in New Zealand.
On completing their training, those who had trained in Canada went on to Europe and those who trained in New Zealand then served in the Pacific, as Cox did.
"Of the total of 13,235 who trained, 4300 were killed - 32.5 per cent," he said.
"However, many deaths were attributed to either bad weather or accidents. Flying is much safer these days."
When asked what Anzac Day meant to him, he said his family, and many other families were affected.
"Within my own family, both my parents lost a brother killed in WWI - generally known then as The Great War.
"My father lost a brother at Gallipoli on Anzac Day, where 2700 New Zealanders died, and my mother lost a brother at Passchendaele in Belgium where 843 New Zealand soldiers were killed in one day, but 12,500 in total along the Western Front in Europe."
He said in WWII, his brother and three cousins served overseas, three in the Air Force and one in the Royal Navy, but none of them survived.
"Kevin was a member of the No 485 New Zealand Spitfire Squadron in England and was killed in a flying accident, his brother Bernard serving in the Royal Navy was killed defusing a German mine in the Mediterranean, and Tony was in No 488 NZ Squadron at Singapore and was shot down and killed in January 1942.
"I was the only one to serve in the Pacific, in No 16 Fighter Squadron, and was one of a flight of 15 RNZAF Corsairs, of which only eight of us landed on my 20th birthday on January 15, 1945, and I was only saved by a flash of lightning. That day is now known as Black Monday."
Cox served three tours of operations in the Pacific in No 16 Fighter Squadron, after which he sailed for Japan on HMS Glory to serve in No 14 Occupational Squadron.
