The Tasman Series was a motor racing competition held annually from 1964 to 1975 over a series of races in New Zealand and Australia. It was named after the Tasman Sea which lies between the two countries. The Tasman Series races were held in January through to late February or early March of each year, during the Formula One off season, taking advantage of winter in the Northern Hemisphere to attract many top drivers to summer in the south. The Tasman Cup was the permanent trophy awarded to the winning driver.
