There are a number of individuals around the country away from the major city centres that are training and endeavouring to start groups in their areas.
When I can, I will facilitate bringing like-minded people together. So drop me a line and we'll see about connecting you with someone in your area. ( firstname.lastname@example.org )
Other than that, the only way to start learning is to take the first step and start the work. Use any resource you can find - articles, videos, this site. There is alot of good information available if you start looking.
Seek out instruction (seminars, travelling), experiment, follow the principles.
The more people involved and training the better for the System here in NZ.
