There's a feeling games will have more chance of selling out at Mt Smart, which can accommodate 30,000 fans, as opposed to Eden Park, which has a normal capacity of 50,000 - 60,000 attended the 2011 Rugby World Cup final.
But it's understood Eden Park and Ateed didn't help their case by trying to incorporate the World Cup into a wider rugby league vision. They hoped to see the venue host more NRL games and even a State of Origin fixture but the World Cup is run by the international federation whereas the NRL and Origin is the domain of Australian league.
The last international played at Eden Park was the 2012 Anzac test and the Warriors have played six NRL games there since 2011.
The venue hosted two games in the 2010 Four Nations as well as the 2008 World Cup match against Australia and the 1988 World Cup final.
Auckland council wanted the Warriors to relocate to Eden Park as part of a stadiums reshuffle but the NRL club received a new licence to stay at Mt Smart until 2028.
Fourteen teams will contest this year's World Cup.
