After the scare, came the response, though, as if the All Blacks were suddenly aware of the criticism which would be coming their way.
Codie Taylor's try on debut after the All Blacks executed a tighthead after the Pumas won a lucky decision from Craig Joubert for a 5m scrum was a case of poetic justice and a step back in the right direction. So was another tighthead on halfway in the final minutes.
During the week, some of the constructive criticism of the pack by coach Steve Hansen might have reached the ears of No8 Kieran Read, who had one of his best games of the year to set the platform for this victory.
Read was intelligent when challenging kick-offs - roaming around the back of the Argentines and allowing for the curve of Dan Carter's delivery - showed pace and awareness down the wide channels where he has traditionally been so clever and destructive in equal turns, and was often brutal on defence. That brutality was ever-present, too, in Jerome Kaino, also much better for his run last week in temperatures about 30C hotter than here.
Read's try - when he picked the pocket of wing Horacio Agulla to score untouched by the posts - was a testament to his line-speed and attacking instincts, but credit too must go to his loose forward partner Richie McCaw, who executed a perfect around-the-ankles tackle to stop a Pumas counter in its tracks and then bounced up and attempted the turnover.
Lock Luke Romano, fully recovered from a black and blue left eye suffered in Apia when colliding with Owen Franks, was another man transformed.
