Sorry but talking from experience one can be a permanent resident without being a NZ citizen and still have a NZ passport I was born not in NZ and have been here 63 years and have a NZ passport
Things may have changed since you got a NZ passport. I came here as a baby, my parents never took out citizenship. I cannot get a NZ passport until such I time as i become a citizen. I am a permanent resident but have to get a resident re entry stamp in my passport to be allowed back in to NZ. The resident re entry stamps last for 10 years. I tried for a NZ passport back in the 80's but couldnt get one then unless I did the citizenship thing. It was simpler and cheaper to get a different passport. I checked it all out again 5 years ago. The current situation is that you cannot get a NZ passport unless you are a NZ citizen.
How's this one, my mum was born in the UK when her parents were traveling, she came to NZ less than a year old, got her education here, her drivers license, her passport, worked here for years, paid taxes, etc. - then when she applied for her firearm license they realised that she was here illegally and tried to deport her.
