We are called Kiwi's because of the flightless bird - the Kiwi. I'd say its our official bird.
Yes it is the Kiwi:
The kiwi is New Zealand's national icon and part of our image world-wide. New Zealanders have been "Kiwis" since the days of the First World War. It's a nickname bestowed by fellow Australian soldiers, and it stuck. Today our identity as Kiwis is based around our national bird.
