The ANZ Championship, also known as the Trans-Tasman Netball League, is a former 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.
