That ISN'T true, just like that, no.
Here
http://www.ird.govt.nz/international...-index.html#02 is the official word from NZ IRD on what makes you a NZ tax resident. As you will see, owning a property in NZ, IN CERTAIN LIMITED CIRCUMSTANCES, can HELP towards your being considered a NZ tax resident, but ownership is not the only criterion taken into account by the Inland Revenue before issuing a certificate.
Also, notice that the criteria for PR are headed 'Acceptable evidence of your
commitment to living in New Zealand.' The authorities are well aware that many foreign nationals would LIKE to have NZ PR, as a convenience, while continuing to live, work and pay into another country abroad while it suits them, which is an arrangement that doesn't benefit NZ. For that reason, the criteria are quite strictly applied and checked out. PR has to be genuinely earnt.
