The All Blacks will come under enormous pressure both physically and mentally at the World Cup and it's part of the reason why they have focused on increased physicality during training sessions.
Assistant coach Ian Foster said it was "business as usual" for the squad, who took part in a training session at Eden Park this morning - with contact being an area of focus that was not necessarily enjoyable.
"It was needed," he said. "Sometimes you don't have to enjoy something but you know it's good for you. What you can't do is go into a massive test against Argentina in 12 days unprepared and not ready for the physicality that's going to come."
Sam Cane described the pre-World Cup training session as "full on", with the flanker wearing the opposing No 7 jersey against Richie McCaw in a training match observed by referee Nick Bryant.
