Internationals Number of NZ born players in the NYC?

I was looking at some of the profiles of the players in the NYC for various teams and was astounded by the amount of New Zealand born players in the teams. For example look at the Cowboy's NYC team:

Sadly, because of these outrageous eligibility rules most of these players will be eligible to play for Australia by the time they're 20-21.

Does anyone have any statistics about the amount of NZ born players in the NYC?
