The quest for just the second Constellation Cup clean sweep and a more complete performance, will drive Australia in the final match of the series in Sydney on Saturday.
The Diamonds took an unassailable 3-0 lead in the four-game series with a 55-43 win over New Zealand in Adelaide on Wednesday night.
It was the seventh time in the eight years of the competition they have held the trophy, but only in 2014 were they able to sweep the Silver Ferns.
"We may have won the Constellation Cup now, but we want to finish four-zip and that's what we're going to aim to do," Diamonds' wing attack Liz Watson told NZ Newswire.
New Zealand captain and defender Katrina Grant says motivating her side for game four won"t be hard even though the match was effectively a dead rubber.
