Argentina have created rugby history, beating the All Blacks for the first time under the Sydney sun, at Parramatta's Bankwest Stadium.
The Pumas produced an inspired, passionate, hungry performance against an insipid All Blacks side, clearly still wearing the wounds of humbling loss to the Wallabies seven-days ago.
In the end, the 25-15 scoreline flattered the men in black, who scored an injury-time try through winger Caleb Clarke - his first for his country in a test.
The All Blacks were suffocated by a ferocious blue and white wall, producing just one line break across the entire 80 minutes.
The writing was on the wall early, with the influential Nicolas Sanchez putting his side in front with a long-range penalty goal after six minutes.
The classy No.10 produced the best 80 minutes of his career, scoring all 25 points, controlling the tempo of the game with tactical kicking and completely outplaying All Blacks pivot Richie Mo'unga.
The All Blacks were guilty of giving away several first-half penalties, gifting Sanchez four shots at goal, which he turned into nine points.
A Mo'unga penalty levelled the scores after 12 minutes, but that was as good as it got for Sam Cane's men in the first half.
Sanchez scored an opportunistic try midway through the half, after his chip kick took a nasty bounce, rebounded of Anton Lienert-Brown's legs and straight into the Pumas playmakers hands, for the opening five-pointer.
The 32-year-old added a further two penalties to close out the half and take a 16-3 lead into the sheds.
The All Blacks lifted their intensity to start the second spell, but made several early handling errors to gift the Pumas field position. Sanchez turned that into another three points, extending the lead to 16, with 30 minutes to play.
Life was breathed into New Zealand 13-minutes later when Cane crashed over off the back of a lineout drive, and when Mo'unga nailed the sideline conversion, the gap was only nine.
But ill-discipline continued the thwart the All Blacks minutes later when Mo'unga was caught offside on defence and Sanchez made him pay with his fifth penalty goal of the afternoon.
The All Blacks dominated territory for the final quarter, but they couldn't break the Pumas resistance, with several handling errors, and two crucial breakdown turnovers my monstrous Argentine skipper Pablo Matera, quelling their attack.
Sanchez nailed a 45-metre bomb to put the game to bed with three minutes to go, to wild celebrations amongst the Pumas non-playing reserves.
The All Blacks pushed for a consolation try and when Clarke found space that alluded him throughout the contest, he dived over to score the first of what will likely be many test tries.
Mo'unga struck the conversion wide and referee Angus Gardiner called time on an historic game of rugby.
New Zealand skipper Cane had no excuses post match.
"They brought more intensity, more line speed," Cane said.
"Their defence was outstanding tonight. We couldn't get our game going and put them under any pressure with the ball.
"Way too many little errors and discipline issues and they kept the scoreboard ticking over.
"We weren't good enough tonight which was extremely disappointing.
"A lot of the lessons there - with test match rugby you have to turn up with the right attitude, right intent every week, or you get it handed to you and unfortunately - we learnt that the hard way."
The result throws the Tri Nations wide open, with three games to play.
The All Blacks will need to win their final game against the Pumas later this month and hope the Wallabies and Argentina split results in their two tests.
Argentina 25 (Sanchez try, 1con, 6pens) bt
