Coming into the 2015 event as champions means the team won't be able to lean on failure as a driver.
"In terms of us as a team and the challenge [of the World Cup] that is something we have talked about," says Smith. "We have got to be as desperate to win as we were back then [2011].
"But no one has won it back to back ... hopefully we can get to that level of desperation, that level of want, so we can get another result."
Having dealt with his disappointment over the Super Rugby final, Smith is ready to throw himself headlong into what will be his 12th and last season with the All Blacks and be one of the key leaders in preparing the side for what lies ahead.
The main aim will be to lift the Apia benchmark and to that end, Smith says, what will be on view in Christchurch will be the type of rugby both teams will take to the World Cup.
"You can't hold too many things back," he says. "You have to try things and you have to try things in the heat of competition otherwise it is too hard to introduce.
"By and large, the way teams play - and that goes for all the Rugby Championship sides - in the next month or two, will to a large extent be the way they play at the World Cup. There will be moves, set-piece plays that will change a little bit but we have got to practise the way we play. We are not good enough to hide it and then suddenly flick a switch come the quarter-final and try six new things. It just wouldn't work."
On a personal level, Smith says he's in a relatively good head space despite losing the Super Rugby final in his last act as a Hurricanes player.
He says the All Blacks are too big an entity and demand too much of each individual for him to be anything but fully absorbed and committed. He's also been invigorated by the return of former backs coach Wayne Smith as a technical adviser.
"He's already stamped his mark. It is great to have him back. He has obviously been one of the biggest influences in my career.
"I think he will add quite a bit to the team and his vision for taking the team forward is great.
"You put your heart and soul into something and for it to come to an end - not the end I wanted - it was tough to take. Coming back in ... [to the All Blacks] and have this challenge [is a good thing]. It is amazing how quickly things are forgotten."
