*Sigh*.. ok I will dumb it down for your benefit.
NZR gave up use of Eden Park to allow NZS to joint bid for the Women's World Cup that required no games played on its venues for the preceding month, during and slightly after the cup was running. The Next biggest Stadium, not in use for that time frame was Mt Smart.
As for the Government, since they agreed to the fifty million outlay for the FIFA world cup, there have been a lot of grumblings about "wasting money" on it. This has only got louder since the cyclone caused billions in damage and lost income and the country now being in a technical recession. It is also an Election year now, so the Govt wont be "giving" money to anything considered non essential least they be considered wasteful with public purse.
I don't think i can dumb it down any more than that.
