Vintage NZ vacation films found but photographer is unknown?

These vintage, 16mm vacation films were recently discovered at a garage sale in San Jose, California. Although they were in very poor condition, they were nevertheless digitally converted courtesy of The California Pioneers of Santa Clara County. This unknown photographer and his wife traveled throughout the Pacific region; including the north and south islands of New Zealand. The historians at California Pioneers of Santa Clara County are hoping, by some wild chance, someone in New Zealand might be able to help provide the identity of this unknown visitor/photographer from California back in prewar 1940. Perhaps someone in New Zealand can recall a visitor staying in their home, or making contact with him?
