The 1948 one was Kaori, 81

Karori is another suburb of Wellington.
From the Karori Cemetary Website
Karori Cemetery is New Zealand's second largest burial ground, covering 40 hectares.
About 80 000 people are buried there.
Therfore it is highly probable that somebody from Newtown would be buried in Karori Cemetary.
Thus this appears to be a very good match with the John E Miller.
Amazingly, the Karori Cemetary web site has a searchable index, and this is the relevant entry.
Last Name: ........ MILLER
First Name: ....... JOHN
Age: 81 Years
Deceased Date: 30-07-1948
Service Date: 03-08-1948

I have double checked the other death entries at the NZ BMD site and I am fairly certain only this entry can
relate to the John Miller in question, so I have paid the NZD 26,00 for a death certificate and will now be waiting
one to two weeks for that to arrive in my mail box.
