Australian defender Courtney Bruce was a constant thorn for the Silver Ferns as the Diamonds surged out to a 14-9 first quarter lead.
Experienced New Zealand shooter Ameliaranne Ekenasio has been rested for the tour, replaced by the Southern Steel’s Georgia Heffernan on debut at Wembley.
Heffernan partnered Grace Nweke in the shooting circle, while the midcourt featured centre Maddie Gordon and wing defence Karin Burger.
Mila Reuelu-Buchanan and Whitney Souness shared the wing attack duties.
Australia pushed on from their five-goal lead at the first break to a 29-22 halftime advantage.
New Zealand’s best passage of play came in the third quarter with Nweke scoring 14 goals for the quarter as New Zealand trimmed the deficit to 44-39.
With the match set for a tight finish New Zealand faded badly, outscored in the last quarter by eight goals.
Silver Ferns coach Noeline Taurua says there will be plenty to address before the team plays Uganda on Monday.
“It was disappointing how that last quarter ended but overall, it was not too bad,” Silver Ferns coach Dame Noeline Taurua said.
“Our ability, once again, to hold right through, our ability not to turn over ball and probably our fitness levels let us down a bit but it’s a start, we know where we’re at, so know the gaps and what we need to improve on.”
