New Zealander's are called 'kiwis' (after the native bird)?
Do New Zealanders have a song about the kiwi?
I know Australians have a (actually still copyrighted and became part of a copyright row with Men at Work's Down - A Land Down Under - it was ruled the latter stole a few notes and had to pay) song about the Kookaburra - even I learned that one in UK childhood - Kookaburra Sits in an old Gum Tree - but I don't know what NZ has.
A song I know that has been liked by people I've encountered (online) from NZ is a modern shanty style song Mollymuak/MollyMawk/Southern Ocean but that refers to Cape Horn and I don't think originated from NZ. (For those who may not know, a mollymawk is an albatross).
