The intensity of the match was evident from the opening whistle at Nelson Mandela Bay Stadium. Just one week prior, Argentina had been dismantled in a 56-17 defeat to South Africa, trailing 36-0 at one stage. Despite that result, Los Pumitas entered the clash in Gqeberha with a focused tactical approach that put immediate pressure on the Baby Blacks.
For the first ten minutes, New Zealand was pinned deep in their own territory, forced to defend multiple phases on their own goal line. While the Kiwis managed to escape that initial onslaught without conceding, the pressure was a clear signal of the shift in momentum. Argentina played with a clear intent to control the pace and territory of the game.
Breakdown dominance and the first breakthrough
The contest was heavily influenced by the struggle for possession, specifically through the battle for the ball at the breakdown. After an early try was ruled out by the TMO for a prior infringement, Argentina maintained a sustained attacking presence that restricted New Zealand’s ability to enter the opposition 22.

The deadlock finally broke in the 15th minute. The sequence involved effective counter-rucking and quick distribution. Argentina won back possession inside the New Zealand half through powerful work at the breakdown, then shifted the ball rapidly to the short side. This created a two-on-one situation that allowed Federico Serpa to hold off a final tackle and score the opening try.
Serpa’s influence extended beyond the try-line. After missing the conversion, he stepped up minutes later to slot a routine penalty, pushing the lead to 8-0. This early cushion allowed Argentina to absorb the inevitable New Zealand reaction with composure.
Discipline failures and the yellow card swing
New Zealand’s response was erratic. While captain Haki Wiseman managed to cut the deficit to 8-7 after 33 minutes, the Kiwis could not solve their discipline issues. The most critical turning point occurred just four minutes before the halftime whistle.
Referee Ella Goldsmith determined that the frequency of penalties conceded by New Zealand near their own line had become excessive. The result was a yellow card for Crusaders lock Jake Frost, who had jumped across illegally at the lineout. The fallout was immediate and severe.
The penalty try sent Ethan Webber to the sideline for ten minutes as well, leaving New Zealand to fight through the closing stages of the half with only 13 players. Despite this numerical disadvantage, the Baby Blacks managed a late score through JD Van Der Westhuizen to bring the halftime score to 15-12, but the damage to their discipline had already set the tone for the second half.
Interceptions and the historic margin
The second half saw New Zealand regain possession and control of the game’s tempo, even while playing short-handed for a period. However, Argentina’s ability to strike at critical moments—a hallmark of championship-level rugby—proved the difference. In the 55th minute, the match’s defining moment arrived when Luciano Avaca intercepted a pass from Oliver Guerin, racing the length of the field to score.
This interception shifted the momentum away from the New Zealand attack. While the Baby Blacks continued to press, Argentina’s defense remained resolute. The tension peaked in the final minutes as New Zealand attempted a late surge, scoring two consecutive tries, though the final effort was ruled out by the TMO. This decision provided the breathing room Argentina needed to secure the 25-17 result.
According to Rugbypass.com, this was a famous victory
for Argentina, defined by a scenario where ill-discipline bit the Kiwis hard. The final scoreline reflected a try-count differential of four to three, but the tactical narrative was much wider: Argentina’s clinical execution versus New Zealand’s instability.
Tournament implications and what to watch
This result fundamentally alters the trajectory of the Rugby Championship U20 for both sides. For Argentina, this isn’t just a win; it is a psychological breakthrough. Moving from a 36-0 deficit against the Junior Boks to a historic victory over New Zealand demonstrates a resilience that will make them a dangerous opponent for the remainder of the tournament.
For New Zealand, the focus must now shift to their set-piece discipline and ruck management. The inability to avoid penalties in their own 22 proved fatal in Gqeberha. If they cannot tighten their discipline, they risk further upsets against sides that can now see a blueprint for defeating them.
Looking ahead, the primary metric for New Zealand will be whether they can stabilize their forward pack and avoid the yellow-card cascades that defined this loss. For Argentina, the challenge is to maintain this intensity and ensure that the confidence gained from this historic win translates into a consistent run through the standings.
