I always found when I travel on NW the question when you get to the check in desk - where are you travelling to today Sir- when i have already handed you my ticket - but then I guessed they were checking that the ticket is correct as to where you think you are going.

Sometime at Customs and Immigration in New Zealand I have had some strange questions, so it seems like they don't scan the information they have anyway.

I guess it complicates things as I was born in NZ but never held a NZ passport, I am entitled to citizenship as a birth right. Living in Australia for most of life Australian ( my dad was an aussie) always seemed to be a better option.

I got a secondary at Customs once - and had trouble explaining the the guys who had a mindset he was dealing with a returning Kiwi - that I was an Aussie on holiday.

Under Freedom of Information - maybe its possible to see your data - but in this current climate - maybe thats classified.
