Douglas Webber Events director Craig Douglas said international television companies ESPN, CBC (Canada), Fox (United States), the Sky network and TVNZ wanted a third game in the series in Dunedin.
"We had planned just to have games at Auckland and Christchurch," Douglas said.
"The Dunedin Ice Stadium will host the decider."
Douglas said the three games in July-August would be broadcast to millions of viewers globally.
The promoters intend to bring some of the stars of the National Hockey League (NHL) and American Hockey League (AHL) to New Zealand.
"The 22 players in the Canadian and United States teams have been recruited from the top ranking leagues," Douglas said.
"They are the best players available to us."
The tour is led by NHL player Kyle Quincey, who will captain the Canadian team.
He is a defender for the Colorado Avalanche.
The United States' captain is Rob Schrenp, of the New York Islanders.
"It is heavily documented in the North American media that these two boys don't like each other," Douglas said.
"They are fierce competitors and have had a lot of run-ins in the NHL league."
There is an intense rivalry between the United States and Canada, two of the giants of international ice hockey.
Canada won the gold medal at the Winter Olympics last year.
Douglas expects everyone in the two squads for the series to be an NHL player or draft player, recently retired NHL player, or an American Hockey League player.
One of the former stars is Daryl Shannon (United States), who retired from the NHL two years ago after playing 544 games.
The cost of producing the three-match series is $1.2 million and early ticket sales suggest that the promoters will recoup this.
The events will be played at the Vector Arena in Auckland (capacity 8700) on July 23, CBS Canterbury Arena (7600) on July 30 and the Dunedin Ice Stadium (4500) on August 3.
Dunedin and Auckland have already sold half the seats for their games.
The crowd capacity in Dunedin is normally 2500, but an extra 2000 seats will come from a temporary grandstand erected over the curling rink.
Dunedin is the only ice stadium in New Zealand that has the capacity to hold such an event.
A portable hockey rink is being transported from Europe for the games in Auckland and Christchurch.
The NHL spec floor and dasher-board system is a full size arena with dimensions of 60m x 30m that will take a week to erect, Douglas said.
"It will be the biggest promotion that ice hockey has ever had in New Zealand," Douglas said.
But it is not just about the game of ice hockey.
"We want to make it an entertainment for the whole family and are bringing NHL announcer Terry Toulet to call the three games," Douglas said. "He has been inducted to the Ice Hockey Hall of Fame."
There will also be a cheerleader squad and big screen television in the arena.
