The Silver Ferns have missed claiming a clean sweep over their Australian rivals, losing the third Constellation Cup test 59 - 53.
But having won the first two tests, the Ferns were awarded the Cup for the first time before a Christchurch crowd of almost 5500.
The Silver Ferns came out fighting and led 20 - 15 at the first quarter.
But the Diamonds gradually clawed back the lead, ending half time ahead 32 - 28 and then dominating the third quarter.
The Ferns closed the gap in the last quarter but fell short with the final score 59 - 53 to the Australians.
It was the first netball test Christchurch has hosted since the region's earthquakes began in September 2010.
And the crowd showed their appreciation, beating their thundersticks at every goal from the national team and cheering as they collected their first Constellation Cup.
