Diamonds 44
Silver Ferns 41
The return of vice-captain Irene van Dyk could not prevent the Silver Ferns losing to Australia 44-41 in Melbourne.
The Diamonds' victory gave them the Constellation Cup and again came in the final stages after New Zealand had powered to an early lead.
Van Dyk took the court ahead of Cathrine Latu, after the 39-year-old watched Wednesday night's defeat by the Diamonds in Adelaide from the reserves bench.
Her greater experience was valuable in the physical match but Australia took control late in the third quarter.
