Sorry, I have just seen your reply.
James and Mary Jane marriage. This James is one of the sons of the James I am looking for.
Interesting to note the 1990 electoral roll. James did have a brother William but I do not know if he came to NZ.
The James/Jane Mackie in Wanganui is worth a look as I know that at one point he was in Palmerston North. If only the family were more creative with the names. James Mackie is very common!.
Thank you for your help.
