Australia is one win away from regaining the Constellation Cup after dominating New Zealand in the second netball Test match in Sydney.

Coming off a 17-goal win in Melbourne, the Diamonds repeated that feat on Wednesday and took a 2-0 lead in the four-Test series with a 68-51 win.

The hosts made the perfect start, capitalising on mistakes to take a 19-13 lead into the first break.

Needing to respond in the second term, the Silver Ferns produced some of their best netball to narrow the deficit to two goals, as the Diamonds took a 30-28 half-time lead.
