"So I just grabbed hold of him and then by the time I felt confident he was fine we were back to last.
"I looked up and thought, okay, we're in trouble now."
Trouble morphed into triumph after Akuta got half a cart into the race before the 400m mark, from where it looked like he was shot out of a giant slingshot, coming off the final bend so fast his legs hardly knew where to land. A few seconds later he was 10 lengths clear and harness racing had a new superstar.
"That was special, he might be a special horse," said Purdon, who has driven more special horses than anybody in New Zealand history.
"The last time I won a big race that easily was Lazarus in the New Zealand Cup but he led that day.
"Young horses rarely even try to win like that."
Akuta was one of three winners on the Jewels for young trainer Hayden Cullen, who runs New Zealand's biggest harness stable these days with plenty of help from Purdon and Natalie Rasmussen.
While Cullen and Akuta take took top billing on the all group-one day there was stiff competition from Tony Herlihy, who trained and drove Double Delight and Bolt For Brilliance to win their respective trotting Jewels, both from seemingly horror draws.
Herlihy's drive on Bolt For Brilliance won him the race, securing tactical advantage early over key rival Muscle Mountain but Bolt For Brilliance was still supreme with the promise he may be even better in the seasons to come.
Bettor Twist provided the early spark to the day with a remarkable win in the three-year-old fillies pace, refusing to yield even through she was wide the entire race while a late change of tactics saw B D Joe lead and hold off a no-excuses Krug in the three-year-old male pace.
Five Wise Men was simply too good in the three-year-old trot to complete a totally dominant season while South Coast Arden's late-season resurgence continued with a bullying victory in the four-year-old male pace for trainer Brent Mangos.
Breeding and syndication giant Breckon Farms had a monster day as did champion sire Bettors Delight, who not only sired five winners, including Need You Now and A Better You, but is also the damsire of trot winner Double Delight, who is actually bred to pace.
