Some scraps of info:

PUREWA CEMETERY (East Auckland) Cremation Register:
DEAN Norman, 3 Sep 1982; of 7 Lintaine Place, Glen Innes
DEAN Zilla Mary, 31 may 1991, 88y, of 2 Lintaine Place.

(NB: suspect that either 2 or 7 is correct; that one entry was not clearly written and consequently transcribed incorrectly)

I'll check the newspapers for any entries.

ARCHWAY (ARCHIVES NZ) in Auckland have probates for:
DEAN Norman, Auckland - filed 1982
DEAN Zilla Mary, widow, Auckland - filed 1991
