Netball New Zealand has confirmed the Silver Ferns will go up against Australia on both sides of the Tasman in October.
The Silver Ferns will defend their Constellation Cup title when they meet the Diamonds in a four-test series.
The rivalry resumes with Silver Ferns' first trip to Australia since late 2019, playing in Brisbane on 13 October and in Cairns four days later.
The Constellation Cup then moves to New Zealand where the two teams go head-to-head at Spark Arena in Auckland on 21 October and TSB Arena in Wellington on 24 October.
Netball New Zealand chief executive Jennie Wyllie said there was plenty of world-class netball to look forward to after such a disrupted international calendar last year.
