Confidence doesn't seem to be an issue for Smith on the field but the All Blacks coaches still believe he has work to do in the area of self-belief.
After mainly being used as a substitute since his All Blacks debut 15 tests ago in 2009, Smith has started the past three. He played 80 minutes in Auckland and was replaced late on in Christchurch and at Yarrow Stadium.
Backs coach Ian Foster agreed Smith had benefited from his time in the No14 jersey, the selectors resisting the temptation to try him at centre.
Smith's combination with fullback Israel Dagg has been excellent and there was a new component in the back three on Saturday with the addition of Rene Ranger on the left wing ahead of Julian Savea.
"Ben has obviously been a big part of that [back three combination]," Foster said.
"He brought great form into this campaign. I think the last three weeks he has grown and I thought he looked settled.
"It was always the plan to give him three in a row in that position because we really felt it would give him a lot of confidence ... and he showed that."
Smith's performances in the three tests were one of the main positives for Hansen. He was consistent under the high ball - an important role for the modern wing - but carried on his broken-field running for which he has been receiving continued plaudits at the Highlanders.
"For me, I enjoy counter-attack, that's something I enjoy doing, having a bit of a go when it's on. You've got to use the attributes that you've got."
Asked about the potential to move to centre following Conrad Smith's sabbatical, Ben Smith said he would play whatever role for the team he could.
