Dawn. Good to see you here.
With regard to accommodation, if you're looking to rent a place, there's a selection of
real estate agents on the NZ Website List at the top of the Making the Move category. Look for Real Estate. I can't guarantee that all links are still functioning as companies do like to muck about with their websites without notifiying me first.
Here's a general overview of
schooling in NZ to get you started. If your youngest is 5 this year she can start school on her 5th birthday. I posted another couple of links about schools on another thread yesterday if you haven't already come across them. Hopefully, if you have some specific questions about it you'd like to post on here, other members who already have children in school in NZ can fill you in.
