The key criteria that captures more people is the 'enduring relationship to NZ' test.
IRD can consider any number of factors in deciding whether you have an enduring relationship and anecdotally they have widen the net in this area recently.
IRD have a guide on the
website which highlights some of the factors they consider, which include personal property like cars, and furniture. They also consider if you have intentions of returning to NZ or have any social ties (family, memberships or networks).
Previously I would have expected that you probably would not be recognised as a tax resident in the following tax year, though with recent changes in IRD interpretation this is more uncertain. Once you are recognised as a tax resident, it is becoming increasingly difficult to 'cut' that status.
Hopefully others on this site who work in the tax area may be able to provide more guidance on how IRD currently view this area.
