However, in "Nationality" on my passport, it has "New Zealand". Since I've never held another nationality, I don't know whether this is just a short hand or not.

On mine it has 'British Citizen' which can be shortened to 'British'. I'm beginning to suspect that 'New Zealand' may be correct - despite what people say or think.

Question: What do you call people from the Greek island of Lesbos? Lesbosians Hands up all those who thought of something else?
