Passengers do know the difference, I have heard passengers say why is everybody on the crew a "kiwi"?
Bro, people are not as stupid as you may believe, it is noticed. You may pull it off on a Trans Tasman, but doing flights out of Australia to places like Fiji, Vanuatu, etc. (ie. no NZ connection to this sector), people notice these things and do comment on them.
