Welcome to ABB CC from a fellow host in New Zealand.
Have you applied for local Council Consent?
Do you know if there's any existing bores/ wells anywhere on the property?
Maybe check out listings or those who have posted from in the area here in CC searchbox where they are in your rural area and msg them to see if they can provide any recommendations of suppliers.
Have you investigated if you will be able to access internet services?
Some regions to this day don't have access or provisions for it so that is also something to factor into account.
All the best for your new venture.
