Hi zumaro
I'm not sure why it has been suggested that you start a new thread seeking a look-up of this Divorce file
The POORE Divorce file as you are aware, is still under the
100 year restriction - with access to same not being available until at least the
end of 2019.
It is a usual courtesy to provide a potential volunteer with the Archives file reference number (in this case it is not available on Archway website - you'd need to request this from Archives New Zealand, Wellington office). But even armed with the ref. number, access to the file may still be denied (to) the volunteer (because of the restriction which is in place.)
My recommendation is that you contact Archives New Zealand (Wellington) - firstly to obtain the POORE Divorce reference number, and, secondly to learn what process you should follow to obtain access to the file ahead of the restriction being lifted.
It used to be that it was necessary to seek an approval letter from a local Court for presentation to Archives NZ before the file could be released. If, (as you're overseas), you plan to have a researcher or local volunteer access the file on your behalf, then it may be necessary to make this known to Archives NZ.
[I've had previous experience with this type of thing - it's a "painless" process
- and Archives staff are most accommodating and helpful.]
Here is a little reading for your interest from the Archives NZ Research Guide on Personal Identity - scroll down to the section headed "Divorce".
