I'm a British citizen. I've been living in New Zealand for a number of years as a Permanent Resident, but have now taken NZ citizenship as well.
I have to return to Britain for a few days as a matter of some urgency. Obviously I can use my British passport to leave and enter Britain.
Can I still use that UK passport with its Permanent Resident visa to return to New Zealand, even though I'm now a citizen?
I'm aware that I can get a NZ passport quite quickly, or a citizenship endorsement in my UK passport, but both options take time and I'd like to be in London by Wednesday if at all possible (earlier if I can manage it) It's early Sunday as I write this.
I never did get a straight answer to this from Immigration NZ. I suspect that the airline will let me board, and although the immigration officer in Wellington might raise an eyebrow, he'd still be obliged to let me in.
Nevertheless, since I'm in the UK for the foreseeable future (although I can't foresee very far right now) I've applied for a Kiwi passport that I should be able to pick up in London in a few days.
