The ANZ Championship, also known as the Trans-Tasman Netball League, was a netball league featuring teams from both Australia and New Zealand. Between 2008 and 2016, it was the top-level league in both countries. The competition was owned and administered by Trans-Tasman Netball League Ltd (TTNL), a joint venture between Netball Australia and Netball New Zealand. It was effectively a merger of Australia's Commonwealth Bank Trophy and New Zealand's National Bank Cup. Its main sponsor was the Australia and New Zealand Banking Group.
In 2008, New South Wales Swifts were the inaugural ANZ Championship winners. Queensland Firebirds were the most successful team during the ANZ Championship era, playing in five grand finals and winning three premierships in 2011, 2015 and 2016. They were also the only team to win back to back ANZ Championship titles. Both Melbourne Vixens (2009, 2014) and Adelaide Thunderbirds (2010, 2013) won two titles each. The most successful New Zealand team were Waikato Bay of Plenty Magic who were premiers in 2012 and were the only team in the competitions history, to contest the finals series every year.
In May 2016, Netball Australia and Netball New Zealand announced that the ANZ Championship would be discontinued after the 2016 season. In Australia it was replaced by Suncorp Super Netball and in New Zealand it was replaced by the ANZ Premiership
