Jaffa or Jafa
Both equally well known in NZ.
The first is a hard coated lolly with a chocolate center and the other is an antagonistic term for Aucklanders (people from the biggest city in NZ, by far). Half of the New Zealander population lives there along with a very high number of folk from South Pacific Islands, notably Samoa (more Samoans live in Auckland than Samoa), but also Fiji, Tonga and Rarotonga.
The term 'Jafa' means "Just Another Farkin’ Aucklander".
