Hey, we live up in Hamilton so not sure if it's the same in Cch but primary schools don't seem to have the catchment zones like the intermediates and highs. If it's a high achieving and popular school it could have a zone though so find out first. We did find though that nobody was particularly interested in talking to us until they knew we were actually in their zone, they defo don't want to be bothered if you're not even in the country yet.
The other thing you may find is that they won't offer you a place until they've seen your work permit or residency sticker and don't forget you have to apply for your kids to study even if you achieve residency.
