1, all 4 Nations are a good cultural fit, Polynesia. Since most of them grow up in NZ anyway, it's almost Origin-like. It's a nice parallel and it doesn't replicate the Pacific/Oceania Cup that will be played in the post season. It would stay the same each year regardless of who's up and down the rankings. Cook Islands against NZ would draw more passion and crowds than Fiji or PNG. The post season tournament would have the best nations by ranking. 2, because all member nations deserve games. Cook Islands need to play someone. PNG and Fiji can play each other annually.
