New Zealand Rugby concedes another domestic competition is a very real possibility in 2021, with Super Rugby Aotearoa proving "it's very much viable".

"That's one possibility we'll consider. We'll be doing what we can to make that competition work."
NZR will also assess whether the North-South match can still go ahead at Eden Park on August 29.
"There's clearly some uncertainty there. We just have to
