I have found a burial record for him.
Died 27 February 1971
Date of birth is stated as unknown, age is given as 49 but how accurate was that I wonder?
He is buried at Waikumete Cemetery, Protestant Division C, Row 2, Plot 75
It would be interesting to obtain his marriage certificate and see what that says. He appears to have married Charlotte in 1949.
I am assuming that you are resident in NZ and therefore would be in a better position to check out his marriage.
The rule for family history is to start with what you know to be correct, i.e. yourself, and work backwards obtaining the relevant certificates to verify what you find.
I'm sure there will be plenty of New Zealanders here who will be willing to help you with Frederick.
