It was a frenetic first half with Argentina full of running in the opening 10 minutes, seeing Rebecchi seize the lead with a reverse stick shot. The Black Sticks were swift to respond and put together a nice phase down the right wing for Kirsten Pearce to smash home the equaliser.
Rebecchi's second saw the visitors head to the break back in front, before the Argentina poured in five more goals in the second spell.
The Black Sticks now head south to Hastings tomorrow in preparation for the Hawke's Bay Cup which starts this weekend. New Zealand are joined by Argentina, Australia, China, United States, Korea, Japan and India at the tournament.
