All Black second-row Brodie Retallick believes his side must improve their performance or risk losing to Argentina in the Rugby Championship opener.
The holders enter the game in Christchurch on the back of a hard-fought 25-16 victory over Samoa, as they found it tough against the islanders on Wednesday.
And lock Retallick, who came off the bench in Apia, has fired a warning shot to his team-mates that another below-par showing could leave them stunned.
"We need to make sure we get our skillsets right and play the style of footy we like. We didn't get a lot of structure on the field, if we can those things right and really challenge the defenders, hopefully we can score a few more tries," he told stuff.co.nz ahead of Friday's match.
"Although it might have been a wee bit rusty (against Samoa), it was our first hit-out and there were some new players out there. But we need to be better than what it was.
"If we perform like that again, we probably won't get the same result. It's obviously a lot tougher opposition and they're going to come over here to look to play, so we need to be a lot sharper."
It promises to be another physical encounter in Christchurch this coming Friday, with the Pumas boasting one of the strongest packs in the game, something Retallick is well aware of.
"The last few times we've played against them, we've scrummed and mauled a lot. It's what they are good at. We expect them to come here and do that again. In terms of where they are as a pack, they're right up there. You could probably even say they're leading the way, especially around scrum-time," he concluded.
