Mostert Blocks Kostecki as 2026 Supercars Championship Stays in NZ

The 2026 supercars championship has spent 11 weeks away from Australia after a reduced-budget decision sent the series to New Zealand instead of keeping the opening stretch at home. It is back at Symmons Plains this weekend, but the long gap has already changed the shape and visibility of the season.

Kostecki Gets Past Mostert

Brodie Kostecki needed to pass Chaz Mostert to claim the Jason Richards Trophy in the final race at Ruapuna in Christchurch. Mostert fought him hard and sent him packing in that race, leaving the trophy decision tied to one decisive battle between two drivers who have helped define the early championship picture.

The Ruapuna result sat inside a season that had already been billed as open. The first four events were described as brilliant, spicy, unpredictable and wildly open, which fits the way the championship has unfolded before the return to Australia.

Boat Freight Changes The Map

Supercars chose New Zealand on a reduced budget and now ships gear there by boat instead of flying cars and equipment across. That move is reported to be almost $1 million cheaper, and it also created a fortnight with two events that kept the championship off the radar at home while the season kept moving.

The series is now at its fifth round of 2026, which is only the third round in Australia. That imbalance is the clearest sign of how much of the first half of the campaign has played out away from local fans, even as the title fight has kept tightening overseas.

Symmons Plains Takes Over

Symmons Plains brings the championship back to Australia after the 11-week stretch without a home race. For drivers such as Kostecki and Mostert, the next phase is less about the New Zealand freight bill and more about whether the early-season openness turns into a real points split once the field settles back on local asphalt.
