Do we need a new name for residents/citizens?

I was talking to a friend whose first language is not English. We got to a topic of slangs and she told me that she thought New Zealanders would be called "Newzzies" because AUStralia = Aussies.

I kinda like that new name? Not more than Kiwi but also almost more?? What is wrong with me

So my question is this. Has anyone heard "Newzzie" before? Could this be popular someday?

Thought it was funny and wanted to share. Have a good day, everyone.
