New Zealand's third defeat from seven games leaves them sitting fifth in the nine-team Pro League, still a chance a making a run in the second half of the competition.
However, it doesn't look as hopeful for their male counterparts.
With the home games part of the schedule nearing an end, the men's side have failed to pick up a victory in their opening six games with the 2-1 defeat yesterday coming after a draw and shootout defeat against Spain on Friday. Seven of their final eight games are on the road and their chances of moving off the bottom of the table looking slim.
Argentina led 2-0 with goals in the first and third quarters before Kane Russell struck New Zealand's only goal in the final quarter.
With one minute remaining, the Black Sticks referred a much-needed penalty corner but it was turned down by the video umpire as Argentina held on for the victory which moved the South Americans to fourth on the Pro League table.
