The Black Sticks have a chance to win their five-game test series against Argentina after drawing the fourth international 3-3 in Rosario today.
Goals to striker Katie Glynn and midfielders Anita Punt and Gemma Flynn ensured the game against the Olympic silver medallists would continue New Zealand's improvement as the series has advanced.
New Zealand lost the first international 4-1, drew the second 1-1 and bagged a 4-1 win on Wednesday.
That suggests steady progress, and captain for the day Punt admitted as much.
"There is definitely more understanding of our structure and we're working together," she said.
