Martin Landajo admits the rain forecast for Saturday in Napier will not help Argentina's new attacking philosophy.
The Pumas have been the surprise package of the competition so far, pushing South Africa all the way in both matches between the two.
However with heavy rain forecast for the clash with the All Blacks, the Pumas scrum-half believes Argentina's attacking game will have to be tweaked.
"We are not accustomed to rain, and we prefer the dry weather," said Landajo, who started both Tests against the Springboks.
"We know it rains a lot in New Zealand so we must adapt.
"The adverse weather does influence the game.
"It certainly does not suit us, or the type of game we want to play, but we have to adapt and we must know how to play all climates."
After their thumping win over Australia, New Zealand come into the game in flying form, and lock Mariano Galarza knows his side will not be able to let their guard drop for a second if they are to record a first ever win over the All Blacks.
"It looks like we'll face rain and wind on Saturday, so this is a good opportunity to get used to what we will experience in the game," Galarza said.
"The key will be to concentrate and continue playing for a full 80 minutes, as there were some lapses that cost us dearly," he said.
