All Blacks endure 'ruthless review' ahead of Bok clash

SPOTLIGHT: All Black forwards coach Jason Ryan says no stone is being left unturned as his side prepares for a mammoth battle against the world's best pack of forwards.

New Zealand did well in the set-pieces and the physical exchanges on their way to a 41-12 win over Argentina in Round One of the Championship in Mendoza.

Ian Foster's side blew the Pumas off the park in the first half, but they found it a bit difficult to keep that same intensity going in the second half.

With the Springboks bosting a powerful pack of forwards, Ryan knows that his squad is facing a very different beast this weekend and that was mentioned in 'a ruthless review' this week.

The story continues below...

"Our scrum stood up and we did have some top-quality ball [against Argentina]," said Ryan.

"It's a different game over there with the sun on your back.

"Mount Smart Stadium [in Auckland] is a little bit wet on a cold, dewy night - she's going to be a title fight.

"It's a different contest this week."

The All Blacks will have to raise the bar significantly, especially after the Boks sent a group of stalwarts over to New Zealand last week to prepare for this Saturday's Test.

"They've sent those guys over early for a reason," Ryan added.

"They'll bring a bit of an edge with them coming over earlier. We've got to be right on.

"They're clear on their identity as a team of who they are around their forwards. Also, I thought they used the ball pretty well [against Australia], a bit of space and got to some edges and trying different things. And they're a good defensive side.

"There are a few things we saw that are a little bit different.

"They're pretty clear on their DNA, the Boks, and you've got to respect them and admire them for it.

"They've got a pretty clear strategy. Put the ball in the air and it will be a hell of a contest."
