The 1964 Tasman Series was an international motor racing series contested in New Zealand and Australia over eight races beginning on 4 January and ending on 2 March. It was the first Tasman Series.
The inaugural series was a battle of the British-based expats, as a two-car team entered under the name of Ecurie Vitesse, led by Australian Jack Brabham. They faced a two-car team of Coopers from Bruce McLaren Motor Racing, led by the Kiwi himself. Although Denny Hulme won the opening round of the series, McLaren a took trifecta of wins in New Zealand setting up the title, but when the teams moved to Australia, Brabham won the first three races, setting up the series for a thrilling finish, however the points system denied that, as Brabham was unable to improve his score, and therefore McLaren emerged as champion. For the record, the last round of the series at Longford was won by the Englishman, Graham Hill, securing a top six points finish in the final standing as a result. Hill won the race at Longford but Brabham was the star, leading until the last laps before transmission failure. 
The most successful of the local-based drivers was John Youl. Although the Cooper he was driving was three-years old, he took the aging T55 to six top 5 finishes. Meanwhile, Australian Bib Stillwell only completed in three races, twice beating Youl, including a second place in the Australian Grand Prix. Another quick local was Frank Matich in his Brabham BT7A, taking pole at Warwick Farm. Whilst leading, his suspension broke and was forced to retire. With a further four retirements, Matich only finished one race he entered, a third place at Longford . 
One score could be dropped from the Australian races and one could be dropped from the New Zealand races, however the dropped races could not include the Australian Grand Prix or the New Zealand Grand Prix. Dropped scores indicated in brackets.
