A cool head saw them go clear in 40.76 seconds with just two to go. Before them Becky Harkerss (Leeston) and Brooklee Smallchange set a cracking pace of 35.32 seconds, but took two rails.
Following Newman came pint-sized 11-year-old Briar Burnett-Grant (Taupo) and the lovely Mighty Maximus. They turned too tight into an early fence, taking a rail, then took the first of the double but managed to pull off some magic to get through the combination, finishing on eight faults in 37.99.
Last to go was Elle Phillips (Waikato) and Fruialishas who pulled back slightly after dropping a rail at the second fence and finished on four faults in 44.13.
Newman has had the 7-year-old pony for three years. She bought him off her trainers Vicki and Amanda Wilson, who taught the horse to jump. This was their first season at grand prix level, and Newman's first Pony of the Year class.
"I was going for a nice steady clear round," she says. "Elle was always going to be the one to watch, though, but Vicki just told me to ride to win."
And for her to win at this level is a dream come true.
"There were lots of tears from everyone," she says. "You don't realise how big the win is until you're there."
Newman credited her trainers and her "good luck charm" Amy Kerr, who always helps her warm up for classes.
Thirty-two started the class and 18 came back for the second round. From there, just four were still all clear, and went through to the nail-biter of a jump-off.
