This is not true of NZ rugby. Essentially Te Whare was a lazy fatty which was why he went from the NPC and Chiefs development down to 3rd division rugby. Nothing to do with politics. The three recent converts from NZ rugby are a fatty last playing 3rd division, a NZ7s ex league player, and a club midfielder who's now a first grade forward, not exactly talent ending up on the scrap heap. Just good sportsmen who were probably never going to make it big in NZ rugby.
For this discussion you need to seperate what you belief Oz rugby is and what NZ rugby actually is. But as you rightly note you hate the sport and that hatred blinds you from being able to have a rational discussion about this.
