It is more than likely some national records were broken at the Northland Memorial Community Centre, but the video footage and results have to be verified in the United States to confirm them.
Pollero also teamed with Whanganui's Marina Cosford to come 11th in the Doubles Overall event with a 13.443s, with the title unsurprisingly won by Carter and Wang (7.680s).
Cosford was in the North Island Medley team that came third in the Timed 3-6-3 Relay Overall, out of six teams, while Pollero, Harper and Chant were part of the The Turtles team who were fourth.
A St Mary's pupil, Pollero had won the novice division at the National Sport Stacking Championships in September last year, which was held on home turf at Cullinane College.
