With 400 points on the line over four races, the inaugural ITM Christchurch Super 440 had the potential to be a moving weekend in the story of the season, and boy did it deliver.
All four races provided a brutal, breathless display of Supercars action, and it also produced some massive moves both forwards and backwards on the leaderboard.
There are now five rounds remaining until the first berth of the Repco Supercars Finals Series is locked away, and seven until the final field of 10 is set, but a distinct split in the field has already emerged.
At the end of a rowdy Ruapuna weekend, Supercars.com takes a look at the winners and losers as the battle for the Repco Sprint Cup begins to heat up.
Winner: Kai Allen

The South Australian is now a Supercars race winner, and if they were still awarded, he would also be a Supercars round winner. As a result, Allen was the biggest mover in the championship over the course of the Christchurch weekend, moving up six positions, and also finding himself with a big 133-point safety buffer to the Finals bubble.
Loser: Chaz Mostert
On the other side of the Race 13 controversy was Mostert, who found himself with a hefty 30 second penalty against his name post-race. It masked what was an otherwise strong day, having found something he was lacking in the #1 Toyota across Friday and Saturday. Mostert is back outside the bubble, the wrong side of a 76-point swing.
Winner: Broc Feeney

The wild collision between Chaz Mostert and Brodie Kostecki at the end of Race 13 reaped several benefits for Broc Feeney. Not only did it secure him the Jason Richards Memorial Trophy, but it also saw him retake the championship lead off the 2023 champ. Can the 2025 Repco Sprint Cup winner carry on with the job?
Losers: Thomas Randle, David Reynolds
Both drivers weren't the worst effected by the opening lap crash in Race 13, however their Finals aspirations took a huge dent. Whilst teammates Cam Waters and Anton De Pasquale are safely in the bubble Randle and Reynolds find themselves 156 and 216 points away. Pressure will continue to rise if their form can't be turned around.
Winner: James Golding

For the first time in his Supercars career, James Golding has secured multiple podiums in a single season. It was a remarkable charge to steal a podium in Race 12, and although overshadowed by the late chaos, his drive from 10th to fourth in the finale was equally impressive. The longer this form continues, the more likely a Finals berth.
Loser: Aaron Cameron

Another driver caught up was the luckless Aaron Cameron, whose continued woes in races showed no signs of slowing down. Ninth in Race 11 was encouraging, however that was offset by damage in Friday's Safety Car confusion, a penalty in Race 12, and a DNF in the finale. At 305 points away, it's an ever growing challenge.
