Biggest problem for NZ2 is where? no other cities are very big and having RL as a second sport in a small population could be a disaster financially and from a fanbase. I guess if Sky NZ is going to stump up $20mill a year more for another club then that would motivate this current mob in charge. I dont think sharing a team around cities will work anymore than sharing the Tigers around Sydney has. In a direct comparison Perth would be ahead of Christchurch in pretty much every metric right now.
I think the three selling points of NZ2 are...
1 - Possibly more money from Sky for the extra NZ-focused content (they've already upped their money, so this is a big assumption)
2 - Pathway for more NZ talent, close to home - especially poaching RU talent.
(Another assumption.. does it make a difference to NZ talent? Would an NRL team sway RU juniors?)
3 - Potential for more "early Friday" games to be in NZ - 8pm NZ on Friday is the 6pm Friday eastern time slot that's not popular with Australian clubs.
(That's assuming both NZ teams are on board with playing that time slot.. I imagine the Warriors would wanna keep some Sunday afternoon games.. that's been a great timeslot for them)
Some assumptions in there, then.. and to be honest I think Perth makes far better sense BEFORE NZ 2.
