There is a lot of hand-wringing going on in NZ now about the future of super rugby, 5 teams is way too many for an economy one-fifth the size of Oz. Their TV deal is $80m/yr and that includes the all-blacks, a pittance compared to ours.
However if they were in the NRL 4 would probably be fine for a 5 million pop. country.
Forget Pacific Island teams, no money in those countries and no infrastructure, but great for NSW or QLD cup teams and steady streams of talent.
The NRL as an entertainment product has taken the lead over the last decade, but the gulf is widening. The narratives build quickly to add suspense, theatre and pressure, all culminating in interest and fan engagement.
