"If he could cope with the physicality, and he started showing us he could, then he had the game to play test rugby," Hansen said. "If you've got a halfback who can clear the ball as quickly as he can - and that's not being disrespectful to any other halfback - he's just a bit of a freak in that area. We haven't had one like that since Graeme Bachop."
Even so, for Smith, game day dragged painfully. "It was probably the longest day of my life so far."
But, having done what he was selected to do - Dan Carter appeared to relish the extra time Smith gave him - he can justifiably look back on a job well done first up. The haka also held a special place for the former New Zealand Maori player.
"I always got a tingle up my neck when I watched the haka when I was a bit younger. To be a part of that was pretty surreal. I'm pretty pumped, I'll be able to watch that and for once it will be me doing the haka ... it was a proud moment."
Hansen said he is unlikely to change things too much for the second test in Christchurch which means Smith could get another start, but the weather conditions could play a part in that thinking.
"One of the reasons we picked these two halfbacks [Smith and Piri Weepu] is they complement each other with their skill sets," Hansen said. "Obviously Piri's game is very strong when it's that physical contest up front and the weather conditions sometimes make them like that."
