New Zealand U20 retained their unbeaten record against Argentina by taming the Pumitas 43-20 in the second round of The Rugby Championship Under 20 tournament on the Sunshine Coast.

New Zealand outscored Argentina six tries to three to secure a crucial TRC bonus point with a round to play.

Argentina demolished hosts Australia on Thursday but New Zealand showed no initial signs of being daunted by a much vaunted pack. The Baby Blacks were two converted tries ahead after six minutes. 

Hooker Vernon Bason drew two defenders as an anchor in a midfield for a move designed to create swift movement out wide.

Centre Xavi Taele sailed clear and delivered back inside to halfback Dylan Pledger.

Taele and Pledger were two of New Zealand’s best. Pledger cleared swiftly and was sprightly with ball in hand. Taele carried robustly, distrusted precisely and had little hassle containing his comparatively listless opposites. 

No.8 Malachi Wrampling was another to produce a powerful display. In the sixth minute he used his long reach to stretch out after identifying the weak shoulder of an opposing tackler and driving forcefully ahead.

New Zealand scored their third try after 20 minutes with a similar movement that led to their first. This time wingers Frank Vaenuku and King Maxwell combined to send Wrampling clear in the space the wingers would typically occupy. 

New Zealand coach Jono Gibbes warned prior.

This pack that they (Argentina) have here is, I think, probably bigger than the South African pack. They are big, heavy, dense guys and they are really well drilled.”

Argentina lost lock Luciano Asevedo to the sin bin for a high tackle but took out their frustration by winning a scrum penalty. A lineout drive involving their entire team followed and Julian Rossi scored.

After resisting a mammoth Argentina drive before the interval, New Zealand ironically struck with their own ten metre shove shortly after the break.

Soon, however, Argentina would stifle the Kiwis with their dogged but dour approach. Another driving try sliced the deficit to 31-15 and then some rare enterprise.

Reserve first-five Santo Di Lucca proved nifty and that enlivened halfback Agustin Sarelli who fooled New Zealand with a rare snipe to send Ignacio Torrado rampaging away.

The contrast in approach between the two countries was best illustrated when Pledger scored his second try. King Maxwell provided the final pass in a sweeping movement that involved half a dozen pairs of hands.

New Zealand's lineout was more accurate and their discipline defending mauls reasonable given the full frontal Pumas tactics. 

First-Five Rico Simpson didn't miss a shot at goal and was fluid on attack. Openside Matt Lowe was hearty and lock Liam Jock toiled gamely again.
