Captain Anita Punt said it was disappointing to allow Australia to take hold of the game in the first quarter and a gutting result.
"It was a really disappointing performance from us today. We didn't start the way we wanted to and that had us on the back foot," she said.
"We have to be better in situations like this and unfortunately it didn't come off for us today so we will go home, regroup and come back fighting harder."
Australia had the Black Sticks rattled early thanks to two goals in the first five minutes, with Emily Smith and Jane Claxton both capitalising on loose balls in the circle and beating goalkeeper Sally Rutherford.
To compound matters, the Kiwis lost Punt for most of the opening quarter after she copped a heavy blow to the foot and limped from the field. After medical attention she returned after the break.
Mariah Williams added to the tally late in the period to give Australia a daunting 3-0 advantage after the opening quarter.
It was a much more balanced second quarter with the best chance coming just out from halftime when Gemma Flynn dove onto a hard cross from Punt but her deflection went just wide.
Stacey Michelsen sparked some magic in the 34th minute with a brilliant solo run, dribbling side to side and beating six defenders before slipping the ball past the keeper.
But the Hockeyroos kept the pressure on and delivered a fourth goal just seconds out from three quarter time through a strong shot at the top of the circle from Georgia Nanscawen.
Punt pulled another goal back for the Black Sticks early in the fourth quarter when she rocketed a penalty corner drag flick into the top of the net.
New Zealand fought desperately in the dying minutes but couldn't find the two goals they needed to force a shoot-out.
