All Blacks hooker Dane Coles says he needs to up his game against Argentina as he believes his last outing against the South Americans was his worst performance in the black jersey.
Coles said he was mindful of not over-preparing but just making sure he prepared well.
"That last game hurt a bit so I want to go out and perform again I suppose in the black jersey," Coles told the All Blacks website.
It had been a mindset lesson after thinking he could go out and things would happen but he had learnt from the experience.
"It's just about being bone-deep in my prep this week and just going out and backing my ability. I did that, I thought, against the Boks because I prepped well and I'll do the same thing and keep things consistent. I'm looking forward to it," he said.
Against Argentina he will have some different targets in his line-out throwing with Patrick Tuipulotu getting a start with Sam Whitelock on the bench while Liam Squire would be starting on the blind-side of the scrum in Jerome Kaino's absence through injury.
Tuipulotu had different skill sets to Whitelock, Coles felt, with Tuipulotu more of a ball-in-hand type of player.
"He's developed into a pretty good lock and he probably hasn't had too many opportunities at this level but I've seen him at training and he puts some pretty big hits in and he's pretty good at lineout time as well. I'm excited for Paddy, he deserves a chance," he said.
Squire said it was exciting to get a start after two games off the bench.
He said he was aware of the role he had in filling in for Kaino as they had been working alongside each other at training for the past two months and he had been picking up tips from him.
"I know there's going to be a bit of expectation to fill that jersey like he does so it's a challenge," he said.
Squire said the best advice Kaino had given him was to back himself and go for it and not to hesitate while he was out in the middle.
"Trust your game and why you are here in this team," he told him.
