The problem with being a young, under-populated nation in the far reaches of the Pacific Ocean, is that not everyone is keen to stay - and plenty of New Zealanders have the dual heritage required to set up a sporting career elsewhere.
In the case of professional rugby, it's long been the case that those who can't make the All Blacks will look through the family lineage and head to Maesteg, Melrose or Munster - wherever they might be able to settle, impress and win test caps.
Rugby is a career, players are commodities, and if they can export themselves and play on the international stage, then they will.
All Black coach Steve Hansen went on the offensive after the draw in Brisbane. The 15 Wallaby points collected by New Zealand-born, raised and developed Mike Harris was hard for Hansen to stomach.
"I am pleased he [Harris] has achieved his dream ... what I find frustrating is that Australia is trying to build their game and put more franchises in place but all they are doing is putting franchises in place and stealing our players," fumed Hansen. "They should get their own house in order and develop their own."
