Discussions will start after this year's Auckland Nines about the event's long-term future.
This year's Nines, which will be played over Waitangi weekend, is the third year of a five-year deal committing the event to Auckland.
It's been a popular concept, although the number of fans is expected to decline again, and there's likely to be competition from across the Tasman to see it relocate to Australia after 2018.
Duco Events, who organise and underwrite the tournament, are keen to keep it in New Zealand and will look to initiate discussions with the NRL and Auckland council (Ateed) about its long-term future. Ateed will invest $12 million to sponsor the Nines over the five years.
"I think the natural timing is probably at the conclusion of this event," Duco chief executive Martin Snedden said.
