Paerata-Reid surfed the closest heat of the entire event in the third round, eventually placing second to Japan's Takumi Nakamura. He got a buzzer-beating wave to equal up the scores with the heat frontrunners and progress through to the final 16 surfers in the qualifying rounds of the under-16 boys.
"I got hassled hard at the beginning by the kid from Argentina and missed two good waves, then I got a 5.23 and needed like a 4.13 and was getting hassled so hard that I paddled up the beach. I caught a wave with 30 seconds remaining and got the 4.13 and progressed on a countback. I was so lucky."
He finished with a 9.36 point heat total out of a possible 20 points, equal with the Argentinian surfer Filipe Suarez.
However, by way of his highest scoring ride of 5.23 points being better than the Argentinian's (5.03), he progressed in second place behind Nakamura, who was 0.01 points ahead.
Williams was the second surfer to survive the qualifying rounds, blitzing her heat with an 11.90 point heat score to beat her opponents from Japan, Mexico and Brazil.
