Marton's Caleb Arthur has retained his Overall National title after victory at the NZ Sport Stacking Open Championships in Wellington at the weekend.
The current Black Stack followed up his April success at the world championships in Orlando, where he won the 3-6-3 timed rally.
Video posted Monday on the Speed Stacks (NZ) Facebook page shows Arthur completing the 3-6-3 cup formation in a blistering 2.082s at the Northland Memorial Community Centre.
