In a result which does not bode well for the upcoming five tests against Australia - and with Diamonds coach Norma Plummer an interested observer in the crowd - New Zealand struggled from the first whistle to the last to find any sort of rhythm.
In the absence of lanky Jamaican goal shoot Romelda Aiken, Northern Mystics shooter Cathrine Latu picked up goalshooting duties for the World 7, with the Southern Steel's Australian goal attack Megan Dehn as her offsider.
The combination stretched New Zealand's circle defence in the opening stanza, new captain Casey Williams and goal defence Katrina Grant often left scrambling to cover some intelligent feeding well-directed by classy centre and World 7 captain Natasha Chokjlat and Samoan wing attack Frances Solia.
At the other end of the court, Irene van Dyk and Maria Tutaia were put under the hammer right from the first whistle, battling the well-drilled English defensive duo of Geva Mentor and Sonia Mkoloma as well as some occasionally wayward feeding.
The Silver Ferns through-court links looked distinctly rusty, although Temepara George - back after two years' self-imposed exile - started with an absolute pinpoint looping pass into van Dyk as she prowled the baseline.
However as the quarter progressed, New Zealand's timing and communication in the midcourt was misfiring, and consistency suffered as a result.
And while both teams were guilty of coughing up too many turnovers, the World 7 managed to convert possession into points as Latu, looking sharp and with impressive elevation, shot 12 from 13 attempts for the quarter.
Van Dyk also missed with only one, sinking eight from nine, but Tutaia struggled with her accuracy and managed only four from seven.
Things didn't improve in the second quarter, the World 7 piling on the pressure through the midcourt, with 54-cap former Australian international Peta Scholz at wing defence giving Liana Barrett-Chase a particularly torrid time.
With Dehn getting through a power of work outside the circle, and with Latu continuing her impressive positioning and eagle-eyed shooting, the World 7 eased out to a four-goal lead early in the second quarter.
The Silver Ferns absorbed the pressure, and clawed back some of the lead but still went into halftime trailing 22-25 as the World 7 increased pressure on the New Zealand midcourt, and restricted van Dyk and Tutaia to just 11 shots on goal for the 15-minutes spell.
The pair settled into their work, and missed only one shot, but Dehn and Latu were converting enough of the extra possession to extend the lead, between them sinking 12 from 14 attempts.
Silver Ferns coach Ruth Aitken resisted the temptation to make wholesale changes at halftime, the introduction of Joline Henry at goal defence for Grant her only concession to the scoreline.
Henry's combination with Williams slotted immediately into action, her speed on the baseline cutting off a lucrative supply of ball to Latu and forcing hard-won turnover ball.
Henry offered more options in getting the ball through the midcourt, and the Silver Ferns levelled early in the spell, but couldn't maintain the momentum as the Mkoloma-Mentor combination pounced on some tentative feeding around the circle for a steady supply of turnover ball.
New Zealand's midcourt woes continued in the third quarter, too many turnovers providing a steady supply of ball for the World 7 shooters -- or to be precise, for Latu who sank 12 from 14 attempts as the international team edged out to a 38-34 lead with 15 minutes remaining.
Van Dyk and Tutaia managed to put up 15 shots for the quarter, sinking 12 of them as the Silver Ferns battled to make headway against a sharp-looking World 7 attack.
Maree Bowden came on for Barrett-Chase in the final quarter, while Australian Demelza McCloud replaced Mkoloma, but there looked little hope for the New Zealanders as they seemed to struggle to find their rhythm.
In contrast, there was no indication the international side had barely had three days together, as Aust ralian coaches Julie Fitzgerald and Lisa Alexander wisely let their talented line-up play their own game.
Sadly, the Silver Ferns not only couldn't play their own game, they didn't seem to know what it was to start with.
