The Kiwis and Kangaroos could join forces in a match against English opposition in Britain during the time of the Tri-Nations rugby league tournament at the end of the year.
New Zealand Rugby League general manager Peter Cordtz said two other matches outside the tournament were being planned for the Kiwis while they were in Europe.
One was a test between New Zealand and France at a French venue still to be decided.
The other was a fixture between an Anzac side and England A in Cumbria.
Cordtz said the Anzac line-up would comprise players from the New Zealand and Australian tour parties.
While the Kiwis could spend six weeks away if they were to make the Tri-Nations final, Cordtz said test coach Daniel Anderson had not requested further fixtures at this stage.
"His primary focus is the Tri-Nations itself," he said.
"He hasn't pushed us for more games apart from those two."
Meanwhile, North Harbour Stadium in Auckland has been named as the venue for the Tri-Nations opener between New Zealand and Australia on October 16.
The ground is a successful one for the Kiwis, who have beaten the Kangaroos three times in four encounters there.
The two teams then fly to London, where they will meet again at Loftus Road, home of Queens Park Rangers soccer club, the following weekend.
Both New Zealand and Australia go on to play two tests against Great Britain, with the top two sides after the double round-robin progressing to the final on November 27.Like
