The All Blacks were too strong for the Pumas winning 44-6 to reach their fifth RWC Final.
The three-time world champions scored seven tries on their way to victory with Will Jordan getting a hat-trick and Shannon Frizell getting a brace.
Ian Foster’s side entered the match as overwhelming favourites and they showed their pedigree in a match where Argentina could not get a five-pointer.
It was an impressive start by Los Pumas as they dominated possession and forced a penalty to take an early lead with Emiliano Boffelli’s boot.
It didn’t take long for the All Blacks to start asserting their dominance after that and after some sustained pressure inside the Pumas’ 22, the ball went wide and Jordan received the ball from a long pass from Richie Mo’unga before sprinting in for an easy try.
Mo’unga made it seven points with the conversion.
The All Blacks were in again in the 17th minute after some scintillating running rugby and composure on attack saw Jordie Barrett finish off a great period of play with a try. Mo’unga could not find the target with his conversion.
The Pumas’ never-say-die attitude kept the All Blacks busy on defence and after some pressure inside their opponents’ half they reduced New Zealand’s lead to six points with another Boffelli penalty.
However, the All Blacks hit back a few minutes later with a penalty of their own. It was Mo’unga who added the three points to the tally.
Foster’s side eventually ended the first half with another try. After some great stepping and power from Mark Tele’a, the ball went through the hand and it eventually found its way to Frizell to ease in for the score.
Mo’unga found the upright with his conversion, but at half-time it was 20-6 to the All Blacks.
It was more of the same from the All Blacks in the early stages of the second half with Aaron Smith showing his class to evade a number of Los Pumas defenders to score his team’s fourth try.
Mo’unga added the extra two points with the conversion.
With momentum on their side, it seemed like there was no stopping the All Blacks and they were in again with Frizell getting his second in the 48th minute. Mo’unga made it a 32-point lead with the conversion.
Jordan then got his second in the 62nd after some great interplay by the All Blacks inside the Pumas’ half.
There was a blemish for the All Blacks in the 66th minute with Scott Barrett getting a yellow card for cynical play, but that didn’t stop the try-scoring.
Jordan completed his hat-trick a few minutes later with a great chip and chase after he was put into space.
