A new era in the All Blacks could spell an end to their dominance in world rugby, according to a Wallabies great.

New Zealand kicked off their 2020 test season with a thrilling 16-16 draw with Australia in Wellington.

While the match was entertaining and it was encouraging to see a competitive Wallabies side turn up, it will be a result All Blacks coach Ian Foster will likely view as a lost opportunity, and one he'll want to rectify.

Former Wallaby David Campese told Si and Phil he wasn't too impressed with New Zealand's performance, particularly Rieko Ioane's bombed try.

"That's not normal what All Blacks do, I know it's a different era... but that changed the game, that allowed the Wallabies to have some self belief and get back into the game, one little mistake. You could just see little things starting to creep in, that weren't there before."

The second Bledisloe Cup test is this weekend in Auckland.
