The 2021 S5000 Tasman Series, known by its sponsored identity the Shannons S5000 Tasman Series, was the 13th season of the revived Tasman Series that was last held in 1975, and the first Tasman Series using S5000 machinery and therefore the S5000 moniker.[1] It was held in late November and early December 2021. Aaron Cameron, driving for Garry Rogers Motorsport, claimed the Tasman Cup, first awarded in 1964.
