Warriors supporters will be able to watch the NRL grand final at two fan zones in Auckland.
Auckland Council has earmarked $50,000 for fan zones at Mt Smart Stadium and Captain Cook Wharf where the clash against Manly on Sunday will be shown on big screens, TVNZ reported.
The IRB has strict rules around advertising allowed in Rugby World Cup areas, including stadiums.
But, Prime Minister John Key said a "co-operative" approach was being taken to make it possible.
Key said it was going to be a special weekend of sport for New Zealanders with the Warriors in the final and the All Blacks v Canada.
"I'm pleased the co-operative is being taken... to ensure we cater for rugby union and rugby league fans."
For now plans were only being made to show the game in Auckland, the Warriors' home town.
Key will travel to Sydney for the match.
Bars around the city will also be showing the match.
Meanwhile, Air New Zealand said it was putting on a second 747 aircraft for the Warriors game on Sunday.
Fans can buy return flights and a match ticket for $999, staring at 9am tomorrow.
The flight leaves Auckland at 9.50am on Sunday and returns at 8am from Sydney the next day.
The special can only be purchased two seats at a time.
