Meanwhile, Taihape's Hayden Smith was in spectacular form all weekend, winning two of his four races in the 15-16 years' junior 125cc class and finishing runner-up to Mangakino's Maximus Purvis in another.
However, a crash in the remaining race cost him dearly and, although he recovered to finish that race in 11th position, it wasn't enough for Smith to win overall and he had to settle for finishing runner-up to Purvis
