Steve Tew says NZ Rugby is committed to Super Rugby until 2020.

Andrew "Twiggy" Forrest's bold plan for a rebel rugby league featuring New Zealand involvement has been given short shrift by Kiwi boss Steve Tew.

But Tew is not as dismissive of the West Australian billionaire's commitment to the sport of rugby, or necessarily his desire to see the game played at the highest level in his home-town Perth.

At Thursday's announcement of New Zealand Rugby's Respect and Responsibility Review findings in Auckland, Tew told Stuff that he was pleased the Australian situation had been resolved, with the NSW Supreme Court upholding the ARU's right to axe the Western Force from Super Rugby as part of the competition's downsizing for 2018 and beyond.

DANIEL CARSON/GETTY IMAGES Andrew Forrest suggested NZ should get involved in his planned Indo-Pacific rebel competition.

That prompted mining magnate Forrest, a man unused to not getting his own way on big decisions, revealing he would set up and fund an "Indo-Pacific" league which would feature the Force as one of its premier teams.

He also invited New Zealand Rugby to get on board with a competition that would be "the IPL of rugby".

"Not between now and 2020," said Tew of the prospect.

"We're committed to Sanzaar and that's the end of it. We've got our own domestic competition, we've got a Super Rugby competition that we love, and that's it."

The current Sanzaar broadcasting deal runs through until 2020, with foundation partners New Zealand, South Africa and Australia locked in through to then.

Tew said Forrest's threats to set up a rival league as a "new and bright dawn" for Australian rugby was a "predictable response".

He added: "But anybody that attempts to set up a professional rugby competition in this part of the world will see how hard it is.

"At some point in time Australia and/or Sanzaar should probably have some dialogue with him."

Tew admitted that Forrest's passion for rugby in West Australia and his obvious resources suggested he was a man that had plenty to offer the sport.

"But he came into the picture a little bit late. At this stage it's an Australian issue," he said.

"We're working on a long-term strategy for Sanzaar. If there is a possibility of that person, or anyone else, wanting to be involved we'll have those discussions."

The NZ Rugby chief executive was also intrigued to hear of the Indo-Pacific region that Forrest promoted as having so many riches at its disposal.

"I haven't heard that particular title before, but I think if you live in West Australia, Perth's the capital of it.

"We've already seen how difficult it is to bring the Sunwolves into our competition, so we'll see how that goes."

Tew was just relieved that Sanzaar could now start planning for 2018's Super Rugby with some certainty.

"We were always told by our Australian colleagues they were confident they had made good decisions and done them properly, and I guess a pretty thorough judicial process has now confirmed that.

"Sanzaar is now getting on with the draw."
