"The beauty of nines is you'll have the forwards involved as well as the backs. If you go sevens, you'll get young blokes and backs, really. You go to nines, you get the big star forwards as well as the backs.''
Mr Higgins said star players were contractually guaranteed, and the even nature of the NRL would be reflected in the tournament.
"It will be meaningful, the competition will matter, which means people will be on the edge of their seats looking at what's going on the field, rather than at the bar.''
NRL general manager commercial and marketing Paul Kind, in Auckland ahead of tomorrow's draw, said a key part of the tournament's long-term success would be attracting Australian fans.
"I think that will come. There's an interest in Eden Park, it's a good time of year, it's a relatively cheap international fare...I think it's really appealing.''
The event is backed by up to $12 million of ratepayer money over the next five years.
