New Zealand number eight Kieran Read has called for an improved performance from the world champions in their Rugby Championship opener against Argentina on Friday.
The All Blacks host los Pumas in Christchurch and Read knows they can't deliver a similar effort as in last week's match against Samoa in Apia when, despite claiming a 25-16 win, the All Blacks struggled for long periods.
"There are certainly a lot of things to improve on in our game," Read told Fairfax Media.
"The most obvious one is holding the ball. If it is a few degrees cooler on Friday night it might allow us to do that."
Read expects Argentina to take the fight to the All Blacks with their traditional strength – their forwards.
"Certainly we got a physical challenge in some respects against Samoa but the Argies will probably bring it in the forward pack; they will drive the maul, you know, take us on up front," he added.
"We have got to expect that and be prepared to work really hard.
"In the past when we have known it's coming we have done well, so we just have to make sure we really switch into that mentality as forward pack to take it back to them."
