Margaret,
the requirements to be called a Notable are as follows -
1 - must have a wikipedia page (edited to add) OR
2 - must be in the national who's who or the national biography for their country.
For NZ that is the NZ Encyclopedia.
You remember the old 2 volume NZ encyclopedia with the light blue covers? Published around 1966, I believe.
This is the online version

If Jean is not on either of those 2 places than she does not really qualify as a Notable, sorry.
She has to have a NATIONALLY recognizable name and she seems to be just a local celebrity. I have never heard of her before. Sorry.
I am sorry to ask this, but you will need to remove the Notable sticker!!
PS. Jean went to Solway college? In Masterton?
My sister also went to Solway college - in the 1970s...
There is a photo of her wearing the Solway school uniform on her profile!!
