JohnG 我不认同您的这个说法，我查到移民法有这样一条，您看看
Under the Immigration Act 2009, New Zealand citizens
cannot hold any type of visa, including a residence class
visa. If you are a dual citizen and you wish to use your
non-New Zealand passport to travel, you should obtain
an endorsement of your New Zealand citizenship in that
passport. This will allow you to re-enter New Zealand as
a citizen. To obtain an endorsement, you must complete
the form New Zealand Citizen Endorsement (INZ 1174) and
supply the evidence explained on the form.
如果我理解的没错误，就是新西兰公民不可以持有其它类型的新西兰签证，包括居民签证。如果有使用其它国家护照旅行，需要一个新西兰移民局的endorsement在你的外国护照上。这样进入新西兰境内使用外国护照，也被认可为新西兰公民。你需要填写1174表格，出示相关证明申请这个 endorsement。
