Hansen said the All Blacks hadn't started planning for Argentina as that would be disrespectful to Canada, but the truth is the North Americans won't feature much in this week's analysis by the players and coaches.
The main focus will be on refining their own game and if they do that successfully not many teams will be able to live with the All Blacks on the field at this tournament.
The players' speed of feet and minds left the French in their wake following two easy victories over Tonga and Japan, and Argentina won't offer much in the way of attacking threats.
Although Tonga surprisingly tested the All Blacks scrum in the second half of their match, and the French built up a good head of steam in the first 10 minutes of their clash, Richie McCaw's men haven't been consistently challenged at this World Cup.
However, they will have one or two things up their sleeves they haven't revealed yet and they will be confident they are in a good position to push on.
There are some injury concerns among the All Blacks, most notably Richard Kahui's hamstring which is likely to keep him out of Sunday's match, but the casualty ward looks nothing like Australia's who today No 8 Radike Samo on the wing in their final pool game against Russia on Saturday.
