Listen to the Wallabies and the All Blacks took rugby to an untouchable level last month when they locked up the Bledisloe Cup for another year.

Listen to New Zealand coach Steve Hansen and nearly every facet of the world champions' game needs a tweak.

The All Blacks' opening Rugby Championship defeats of the Australia - 27-19 in Sydney and 22-0 in Auckland - should translate into a third win over Argentina in Wellington on Saturday.

However, Hansen was taking nothing for granted and dismissed the comments of Australian counterpart Robbie Deans and several Wallabies players, who said the All Blacks were playing on a different level to the rest of the rugby world.

"I wasn't overly happy with our last performance. I thought we played with great intensity and great purpose but we weren't very accurate," Hansen said.

"We probably ditched about six tries. If you're a coach, you don't want to miss any, let alone six.

"You still have to be happy with the result ... but our accuracy wasn't where it needs to be.

"So once we can get that right, we can lay claim that we've moved up a couple of levels."

While even Hansen had few qualms about the defensive efforts, his team's attacking execution has been dissected this week.

The All Blacks scored just three tries in the two Wallabies Tests and even though they went to fullback Israel Dagg (twice) and wing Cory Jane, Hansen said the outside backs' attack hadn't reached expectations.

Counter attacking from kicks - a New Zealand strength in recent years - was lacking in cohesion, he said.

"We were quite individualistic with our counter and for effective counter rugby you need to use multiple people and use space. We didn't do that particularly well."

Hansen was unlikely to address the problem with personnel changes, indicating he would stick largely with the same team to face Argentina when it is named on Thursday.
