The All Blacks have received a timely boost ahead of their Test with the Wallabies when Cam Roigard was among four returning players who were added to the squad for the eagerly anticipated Bledisloe Cup clash.

Roigard has been joined by fellow scrum-half Cortez Ratima, Codie Taylor (hooker) and Patrick Tuipulotu (second-row) who have overcome injuries and are available for selection for their clash with their trans-Tasman rivals at Eden Park.

After four rounds of action of this year’s Rugby Championship all four of the competing nations still have a chance of winning the prestigious Southern Hemisphere tournament.

Rugby Championship is evenly poised

Each team has won two and lost as many Tests with the Wallabies setting the pace atop the standings with 11 points, one ahead of the All Blacks and Springboks, and two clear of Los Pumas.

New Zealand know that they can ill afford another defeat and will be determined to bounce back after they suffered a 43-10 loss to their arch rivals the Springboks – a record-breaking Test defeat – in their previous match a fortnight ago.

Roigard missed the early rounds of the Rugby Championship due to a stress fracture in his right foot, which he sustained during New Zealand’s three-Test series against France in July.

However, he made a successful try-scoring return to action for Counties Manukau off the replacements in their NPC victory over Auckland in Pukekohe last week and looks set to be rushed back into New Zealand’s starting line-up for their clash with the Wallabies.

And Roigard knows that he has to hit the ground running as the All Blacks hope to win the Bledisloe Cup for the 23rd successive year.

“It was a tough pill to swallow … we got quite a few things wrong in that Test match,” he said of that humiliating loss to the Boks.

All Blacks hint at shock selection call to stifle ‘unbelievably talented’ Wallabies star

“We want to always perform to make New Zealand proud. We had some tough conversations on Sunday and Monday, so we look forward to putting out a performance that makes ourselves and the country proud on Saturday.

“The boys are refreshed … once we got into the review (of the loss to the Boks) there was a bit of an edge and some real honest conversations. They were talking about standards and expectations around where we went wrong and how we are going to get better.

“It’s not a review you want to have. It’s always pretty tough after a loss, and there’s probably a bit more of a look at yourself.

‘Everyone across the group has individual accountability’

“Part of the All Blacks standard is there’s no stone unturned and everyone across the group has individual accountability. It wasn’t a short, sharp review – there were a lot of layers to it.”

And although the Wallabies have come off second best against the All Blacks when competing for the Bledisloe Cup for more than two decades, Roigard is not underestimating Joe Schmidt’s troops.

“They’ve been battle-hardened,” he said. “They’ve had some really big Test matches. They were probably unlucky not to win the Lions series.

“They’re a team that’s going to go for 80, regardless of previous results and history.

“They’re going to come here thinking they’ve got a genuine chance to win. And they’re probably a team that’s going to have a crack from anywhere, especially with James O’Connor coming back.

“It’s that fearless mindset.”
