The 2019 Constellation Cup was the 10th Constellation Cup series between New Zealand and Australia. The series was held in October 2019 and was the first meeting between the nations since the 2019 Netball World Cup Final in Liverpool, which was won by New Zealand by one goal. The series was played over four test matches, split evenly between New Zealand and Australian venues. Despite both teams winning two matches, the series was by Australia with a superior goal percentage. The result ensured Australia stretched their consecutive streak of Constellation Cup titles to seven-in-a-row, which remains the record winning streak of either nation in the fixture.
