"We haven't been playing our best hockey, so to still get the win when we weren't at the top of our game is great," she said.
"We had better patches, I guess. But we still weren't happy with our consistency in some areas, so hopefully we will come out even better again in this next game."
A bit of rustiness was to be expected from the Black Sticks, who are playing in their first tests since their fourth-place finish at the World League semifinals in Belgium. For this campaign, Black Sticks coach Mark Hager has recalled several veterans, including defender Emily Naylor and striker Charlotte Harrison, and Punt said the team have taken a bit longer than hoped to click into gear.
"We've only been back playing as a group since Monday, so our structure and discipline isn't as sharp as it should be."
Meanwhile, Argentina have brought more of a development team to New Zealand, with several new caps in the side, but Punt said some of the young talent coming through are just as dangerous as their experienced stars.
"They're a fast counter-attacking team, much like we are, so it's very fast and exciting hockey when we come up against one another."
Today's match will be streamed live and exclusively on nzherald.co.nz from 5pm, before the Black Sticks men play their opening test against India at 7pm.
