from the view point of making a host nation of world cup show the world that they care about the world cup event as a whole is pretty poor.
The Rugby world cup in Australia gave minnow teams a home away from home like how Tazmania supported a minnow nation and really got behind them, going to their games and egging them on etc.
NZ rugby world cup will follow the same suit.
Its important that the people of a host nation support the "idea" of a world cup, most host nations and the stronger teams are going to automactically get reasonbly or OTT support, its the lesser a teams etc that need to be embraced and feel connected to the district, state or location they have been allocated, the small fish in big pond but they are playing a game you love nonetheless. .
