Hi Michi
If, by all family members, you mean those apart from a partner and children i.e. your immediate family (if you have them, of course
), then they should only be looked at by INZ if you, in the future, want to sponsor them to go to NZ.
If it is only your partner and children then, yes, they would be part of your current application and INZ will include them in their enquiries. They would all have to go to NZ to activate their PR within 12 months of it being granted or they would lose it. If it's only other members of your family e.g. parents, sisters, brothers etc. , they don't need to go to NZ if you are granted PR. They are only included on your applicaton for INZ's information and they don't need to do anything.
