Hansen: We’re still building

All Blacks coach Steve Hansen has insisted that there is no cause for concern after his side's stuttering 43-10 win over Georgia.

The victory secured New Zealand's spot in the quarter-finals of the competition, but it was a performance that would not have instilled fear into their opponents, with defending World Cup champions making basic handling errors while their scrum struggled against second tier opposition.

However, Hansen is not fazed by the below-par showing as he believes his side are still working towards their top form.

"You're just trying to work on certain parts of your game," he explained.

"We are under no illusions that it wasn't perfect out there. I thought the intensity around some of those contact areas was a different step up. 

"There are lots of things that we could have done better. Our skill execution was not great. 

"If we had one problem which I would say is the easiest to fix in this team, it's skill execution. We've got plenty of talent.

"At the moment we're working on some other things, and the things we were working on tonight were pretty good.

"I wouldn't say our game was great but it doesn't have to be at the moment. You don't get any gold medals for winning these games. You just to get to qualify.

"We're in a position now where we can say we're in the quarter-finals which is quite exciting."

The All Blacks, who are the first team to qualify for the last eight, face Tonga in their final Pool C encounter next Friday.
