Searching for information about my Father

Hello. I have been searching for information about my biological father for many years on Ancestry, My Heritage, 123 & me and Wiki Tree plus DNA.

He was born Ronald E***in Watford Hertfordshire UK in 1908 and apprenticed as a baker. He was a sergeant in the UK Royal Army Service Corps working in a field bakery in France and North Africa. After WW2 he worked in Butlins and Hayling Island UK.

Some time after 1950 he came to New Zealand where he reported died in 1969. I lost track of him except for a reported visit back to the UK around 1960 with his wife, Kathy. 

I do have photos of him but would love to know about his life in New Zealand and where he is buried. He did use several different names during his life.

Thank you for your time.
