Mystery solved. Cool !

Yes ... I'd spotted the George and Arthur WYMER on WWI list, earlier.
Their father was Enoch WYMER.
NZ Death1949 - WYMER - Enoch - 79 years (bc 1870)
Seems he may be same chap as on 1881 UK census, living in Norfolk with parents Robert and Caroline ?
There's a UK birth (Norfolk) also for "Arthur Enoch WYMER - 1897" who seems to be the Arthur WYMER serving in NZ Forces WW1 ?
Added: Also UK (Norfolk) birth for George Robert WYMER (March 1896) - NZ Death = 1959 aged 63 years = bc 1896 :
