The series, which consisted of sixteen races at five meetings, began on 14 January at Ruapuna Park in Christchurch, and ended on 15 February with the 60th running of the New Zealand Grand Prix, at Manfeild Autocourse in Feilding.
[1] Stroll won three of the first four races held in the series at Ruapuna and Teretonga (taking the round wins at both circuits) before consistent finishing for the remainder of the campaign allowed him to maintain his championship lead throughout.
M2 Competition team-mate Brandon Maïsano finished the season as runner-up, 108 points in arrears of Stroll.
Four other drivers took race victories during the 2015 season as Arjun Maini (M2 Competition) and Sam MacLeod (Giles Motorsport) each won two races – both at Hampton Downs and Taupō respectively – as they completed the top five in the drivers' championship, with MacLeod taking the round wins at Taupō and Manfeild.
Only ETEC Motorsport failed to take a race win, with a pair of third places from Thomas Randle being their best result.
