"Playing a top-tier team, you need to be at the top of your game, and today we lacked the quality of basics in our tackling and ball control under pressure.
"We have a quick turnaround ahead of tomorrow's fourth game, so the girls will do their recovery and scouting to ensure we go into the challenge on the front foot."
Argentina made a fast start and ran out to an early lead in just the fourth minute, when Maria Granatto deflected into goal from close range.
The hosts doubled their advantage midway through the second quarter, with Eugenia Trinchinetti capitalising on a loose ball in the circle.
Argentina sealed the result from a 36th-minute penalty corner which Delfina Merino crashed into goal after an initial save.
The Black Sticks go up against Argentina in test four at 10am tomorrow (NZ time), with the game streamed live online
