Richie McCaw admitted that aggressive defence has been a focus for the All Blacks after they downed Argentina in Christchurch.
The Kiwi skipper was one of five try-scorers for New Zealand, who ran out 39-18 winners, with their physicality particularly impressive as they shut down Argentina's attack with ease.
They did concede two tries from rolling mauls, but other than that, it was a convincing win for the All Blacks, and McCaw, in likely his final game in Christchurch, felt it was an improvement on last week's laboured success over Samoa.
That bodes well, with a tough trip to Johannesburg to take on the Springboks next up for Steve Hansen's men.
"It was a step up from last week," McCaw told Sky Sports.
"I think we played some good rugby at times. There was a wee patch in the second half where our discipline let us down when it didn't need to and they scored a couple of tries on the back end of that. All in all it was a step up.
"It's pleasing that guys are excited about not having the ball instead of just waiting to get it back. If you can force mistakes at the wrong end of the field, you can cash in, which we did.
"It's a step in the right direction and we've got to reflect on that but you need to look at ways of improving and we'll do that.
"It was nice to get a win in front of this crowd that have been awesome over the years."
