Hi,
I know there is at least one practitioner on this BB who has practiced in Australia and has just recently moved to NZ--so perhaps you will find an answer from him soon.
In the meantime, look at this website for some possible names and addresses:
www.homeopathic.org
There is also an organization in New Zealand with a website and some people who could direct you to pharmacies and practitioners they are affiliated with. I know NZ is another place entirely, but chances are good people know practitioners and services available in both communities. I think there is a link to this site from the HomeopathyHome.com site with which this BB is affiliated.
Good luck to you both,
Divina
