Hi Lillybetts. We have made the decision to home school starting this year when my little girl turns 5.
I'm not sure where you are in NZ, but there are great support groups right around the country that can help you with information about everything you want/need to know. We are in Auckland and took the time to go to one the information evenings run by the Auckland Home Educators. It was invaluable in my opinion :)
I am really looking forward to starting! We have been collecting bits and pieces for it for the last few months and have curriculum/resources from all over the world :) Feel free to PM me if you have any questions
