There were a number of RNZAF pilots attached to 9Sqn RAAF in Vietnam one of whom was Flt Lt Doug 'Punch" Paterson who was awarded a DFC. "Punch" Pattison was a bit of a character before he went to Vietnam. He got his DFC for refusing to abandon his ground-fire damaged Iroquois because, as he put it, "it was too far to walk home", so he brought the aircraft back with him!
There were 30 or so RNZAF pilots flew with the USAF on the Bronco, and with the Aussies on the Iroquois.
