New Zealand would host one of the four pools and at least one quarter-final but would also bid to host a semifinal and possibly even the final. Decisions on this would be made by a working committee set up to oversee the tournament and would be made based on which venue would deliver the best profits.
Another aspect of the bid was to stage one or more games in Papua New Guinea and there has been thought to widen this to Fiji or another Pacific island.
Profits from last year's World Cup are due to be announced soon and are believed to have surpassed the A$5 million made from the 2008 World Cup hosted by Australia.
"We expect it to be one of the most profitable if not the most profitable World Cup in history," NZRL chief executive Phil Holden said.
"You would think that South Africa would be a risky proposition. A key thrust of our presentation was that now is the time to consolidate the gains made in 2013 and set up the game forever. Between Australia and New Zealand, we run these events, we know what we are doing and the passion and interest is high in our community.
"The expansion aspects of including Papua New Guinea are really important in terms of growing the reach of the game. That's another compelling argument."
Stephen Kearney will be confirmed as Kiwis coach on Friday and his first task will be the annual Anzac test, which is likely to be staged in Sydney on May 2. Some findings from the failed World Cup campaign will also be released on Friday, with most interest around the investigation into the use of sleeping pills and energy drinks by players.APNZ
