Catherine, when you get his NZ will it will include his date of death, and from that you can order an NZ death cert which is very detailed. So long as the person who registered his death had the information, it should give details about both his parents as well as his age, how long in NZ, and his wife and child[ren], address, occupation, etc.

I'll be interested to see what you find, if you don't mind posting to the list?
