Just a heads up that there is an established NZ Kings of War group on Facebook. Originally set up by Matt Barker you can access it here
It primarily has information on upcoming events around the country and information from suppliers. I tend to snatch any event info and put it in the Fields of Blood Event Calendar but it does allow you to easily access NZ KoWers in different regions.
I'd recommend that any locals sign up and keep an eye out for regional news and any upcoming events. Resources like this can only help the local community grow. I'm optimistic that we can see KoW establish itself across the country over the course of 2017.
