Fourteen-year-old Malone won a title in 2019 but is surfing in a different age category this year. It appears to have had no impact on his performances.
In the u16 girls, Liv Haysom (Piha) and Natasha Gouldsbury (Taranaki) produced the most convincing performances in advancing to the semifinals.
As well as the two titles on offer for the boys and girls, surfers in the u16 divisions will be vying for national selection this year.
The Health 2000 National Surfing Championships is the first event of the New Zealand Grom Series in the build-up to the world junior championships.
Surfers in the senior divisions at the national champs had a day off yesterday but were due to be back in action today.
Organisers moved the event to Karitane for today's surfing and the waves were expected to be about two metres.
