"It was a good first half from us which we dominated and created a lot of pressure. We fell away a bit in the second half so we know what needs to be worked on ahead of game two."
New Zealand began the game with high intensity and opened the scoring in the sixth minute when Harrison knocked in from a penalty corner.
Curtis doubled the lead 10 minutes later with a tidy finish on a good phase of play up the field.
Midlands youngster Robinson then scored her first ever goal for the Black Sticks from a top drawer piece of aggressive attack.
Neither side could add to the score in the second half as Malaysia improved on defence and caused some trouble for New Zealand on the ball.
The Black Sticks go up against Malaysia in game two at 6.30pm tomorrow.
