"In the heat of the match, playing well, going through phases, (doing) off-loads from the ground, sometimes you overdo things and that's not smart. Those are the bad decisions we're making."
The players are also well aware that in their two matches on the road in Australasia, including a 36-20 loss to Australia, Argentina's usually strong defence was poor, shipping 13 tries.
It will be the teams' seventh clash in the Argentine capital which is where the Pumas have come closest to beating the All Blacks, notably a 21-21 draw in 1985.
The All Blacks snatched victory from the jaws of defeat at the River Plate stadium to win 24-20 in 2001 and won 25-19 in their last meeting at Velez in 2006.
"I think that little by little the gaps are shortening," said winger Santiago Cordero, who scored Argentina's early try in Hamilton.
"We'd never beaten South Africa and we did it twice in a year," he said.
"In any case, we know it will be hard and I fear the same could happen as in the last matches, playing 60 minutes and then dropping our arms.
"I want that to end."
