New Zealand boss Steve Hansen hailed his side's showing in Friday's 39-18 win over Argentina but believes they can still improve.
The All Blacks scored five tries in their Rugby Championship opener in Christchurch but conceded two five-pointers midway through the second half from driving mauls close to their tryline.
And although Hansen was happy with the result, he highlighted the areas which he feels his side must improve on.
“We went up about four or five gears and we needed to, to be honest,” Hansen told Sky Sports.
“We still have a wee way to go but for most of the game we were pretty good.
“There was a period there for about 10 or 15 minutes where we went to sleep a bit and let them back into it, but overall a good pass mark.
“I think we’ve got to work on our chop tackles – at times we wrestled with them – and we still have to get our running lines better.
“The maul; obviously they scored a couple of tries off the maul, so there’s plenty there for us to work on, but we’ll enjoy the moment for what it is – Test wins are hard to get.”
Hansen singled out the All Blacks' backs for special praise, especially the centre combination of Sonny Bill Williams and Ma'a Nonu.
“I thought Sonny (Bill Williams) was very good, both with the ball and defensively," he added.
"He made some big tackles as well.
“I thought him and Ma’a (Nonu) worked well in the midfield.
“That was a combination we wanted to have a look at and both of them did what we wanted them to do so it was very, very pleasing."
