That and the fact that Kiwis are naturally the perfect rugby league players. Bigger, stronger, quicker than their Australian counterparts.
I'll bet that if you look at the junior grades in the NRL and the better amateur leagues, you will see a big percentage of them are islanders of some descent, whether Kiwis or Samoans/Fijians/Tongans.
