Two of New Zealand's closest rivals have responded to their decision to part ways with Sanzaar, in the hope of establishing a new Super Rugby competition.
NZR has revealed plans to ditch the current tournament structure - as well as the governing body - from 2021, following the three-month Aratipu review.
NZR's preference would be an eight- to 10 team competition, which includes all five New Zealand franchises and one Pacific Island team with two to four Australian sides.
It is believed Sanzaar would remain in control of the Rugby Championship.
NZR said they are excited around what Australia can bring to the table, and will be working with them to seek interest from their Super Rugby franchises. From next week, expressions of interest will be sought from the Aussie teams - potentially sparking a fight for survival among the five franchises - before deciding on their participation.
