Smith received a wonderful off-load from No.8 Kieran Read during a blindside move from a lineout ruck to score New Zealand's first try in Hamilton on Saturday.
Another followed three minutes later for Smith when he was 'Johnny on the spot' to touch down after a centring kick by wing Ben Smith which was uncontrolled by Argentina's defenders.
"We had identified there was a bit of space around the ruck and the maul and Reado's off-load, what more can you say about that. All I had to do was catch it so I was very happy to get a cheeky dot there and the other one I let them over-run it and got a lolly, so I'm very happy," he said.
Smith said the deteriorating weather had influenced the game and in hindsight it might have been better to have kept putting the ball into the corners to build pressure.
"We were still building pressure but were unable to keep the foot on the throat because when we got down there we would let them off with a silly penalty at a ruck or a scrum and letting them out of their zone. If think if we had that again we would be a lot better at our decision-making," he said.
It wasn't easy for such a small man against such tall opponents.
"They're big boys and if you give them a target to hit, they will hit you."
It was a help having a pack like that of the All Blacks in front of him, but if there were any slip-ups he did tend to cop it.
"I've always known I've been smaller I just had to be better at other things," he said.
But he said you knew when you had had a good Test match when you were feeling 'bumped up and a bit bruised'.
The loss of skipper Richie McCaw had seen the leadership group in the side take over with No.8 Kieran Read stepping up and centre Conrad Smith and fullback Israel Dagg also keeping the side ticking along.
