I guess no one else here is from Nelson.
I'm from Chch, so if you happened to be down this way would be happy to meet for a coffee. There is also always someone online happy to answer any questions, even though it's not the same.
You could try plunket or La leche league to see if they have a coffee group in your area that you could go to. Churches also often have mothers groups and are always happy to welcome new people.
Hope this is of some help. If there is anything else I can do to help just ask
