The tournament, in which the five New Zealand and Australian teams play cross over games in both countries, is scheduled to start in May.
However the competition is under threat due to Covid-19 travel restrictions, with a trans-tasman bubble needed to make the schedule work.
Currently anyone entering New Zealand or returning from overseas must quarantine for two weeks.
That would make the current Super Rugby Trans-Tasman schedule, which has the Chiefs playing in Perth on the opening round before returning to Hamilton for a home game the following week, unworkable.
