The Black Sticks have left it late to come away with a 2-2 draw in the sixth and final hockey test against Argentina in Mar del Plata.
New Zealand trailed 2-0 with five minutes to play, before Stacey Michelsen and Kayla Whitelock found the back of the net to level the scores.
The six-game series is drawn 2-2.
Coach Mark Hager says being up against it probably worked in their favour.
"We made a poor start to the game and were a bit apprehensive, but the way we fought back was pleasing," he said.
"This trip has been a good adventure for us against a very good opponent and to be able to come away with a series win is a real positive.
"We have identified some strengths and weaknesses from these six games. We came here with some questions and feel like those have been answered."
The Black Sticks now head home to New Zealand to prepare for two tests against Canada over Easter weekend in the build-up to the Hawke's Bay Cup from April 2-10.
