The All Blacks' 57-22 win over Argentina in Hamilton on Saturday didn't truly reflect how much pressure Steve Hansen's men were actually under by the gallant Pumas.
Argentina turned up and they were willing to chance their arm against the number one ranked rugby team in the world, creating havoc in the breakdown and taking their opportunities when they could.
Veteran All Black Jerome Kaino admitted the starting forwards were a little shell-shocked by the pace at which the game was being played at.
“We pride ourselves on quick ball and Aaron (Smith) to have an easy night and in that first half we didn't do that, we didn't provide it," said Kaino.
"As a pack we took that personally and that is one massive area we want to improve on this week."
But the All Blacks machine adapted to the South Americans' tactics, bringing on an array of changes in the second half which blew the game wide open.
Kaino, 33, credited the impetus that the bench players brought onto the pitch when they entered the game.
"We pride ourselves on our fitness and for the guys to weather that storm in the first 50 (minutes) and change gears; our bench came on and added a lot of energy."
Sam Whitelock, 27, agreed with his teammate Kaino, with the lacklustre way the team started against the Pumas.
"We didn't really have a good night. It is something that we are going to be looking at this afternoon as we have a forwards meeting just around what the issue was and how we can improve it," said Whitelock.
The Springboks suffered their second straight loss in the Rugby Championship on Saturday at the hands of the Wallabies, going down 23-17 in Brisbane.
The South African side will be looking to bounce back against an in-form New Zealand team.
Whitelock believes the All Blacks' forward pack needs to plug up some major holes which the Argentinians identified, making sniping runs in and around the breakdown area gaining good positive ground.
"Going forward it is going to be critical against a good set piece team like South Africa.
"One of the really big positive things for us was we adapted on the run rather than waiting for the game to finish and sorting those issues out."
The All Blacks take on the Springboks this Saturday in Christchurch at 7.35pm.
The last time the two sides met was at the 2015 Rugby World Cup in London where the All Blacks edged South Africa 20-18.
