I have dual AUS/UK citizenship but have been living in NZ for the last ~14 years and over COVID decided it was time to become a citizen there (a relatively easy process for an Australian - something that ended up being quite helpful as I had to leave NZ during COVID to visit my very sick father in the UK which may not have been quite as smooth as non-citizen), so I now have 3 passports.
Prior to COVID I traveled trans-tasman a lot for work and would always just use my Australian passport without issue. However, if I went to the UK, I always used to leave/enter NZ on my Australian passport and enter/leave the UK on my UK passport. (Same when I lived in Australia and would travel to UK). I have always done this as an older colleague with dual passports, told me ages ago that countries don't like you entering and leaving on different passports (as I assume that means they lose track of who is actually inside their borders). This approach has always worked and I have never had any problems.
So for my first trans-tasman trip post COVID (God bless Microsoft Teams!) I thought I would use the same strategy, with my NZ passport at the NZ board and AU passport at the Australian border. In all cases (except leaving NZ) the smart gates rejected me. In Australia, I put this down to having a new Australian passport, but when directed to an agent at Auckland airport at 1am this morning, he told me that the smart gates won't work unless I use the same passport at each end and said I should just travel on one passport. But while chatting to the immigration agent while existing Australian and she asked me if I had dual nationality and I said I did, she said I must leave Australia on my Australian passport (which I was doing).
Any other AU/NZ dual passport holders here who have found out which method works best and keeps them all happy?
