"Our cross country result was better . . . closer to the time, and it was a really tough track out there. Yesterday was make or break for us and what it shows though is that we are ready for the next level," Pottinger said before collecting the silverware.

Brooks was also over the moon with his result.
"I just couldn't have done any more nor be more proud of him," he said of For Fame, a 7-year-old New Zealand sport horse.
Matangi's Samantha Felton and Ricker Ridge Sooty GNZ were comfortable winners of the Bats CCI2* Championship, finishing on their 28.1 dressage score.
"There's quite a lot of pressure when you are sitting on a good jumper," said Felton. "This is a great way to finish the weekend ... actually a good way to finish a challenging year."
Felton said she was confident the 7-year-old, the youngest in the field, was destined for greater things.
"We want to do this at his pace and produce him properly," she said of the horse she co-owns with Pip McCarroll. "I really rate him."
Felton was one of the busiest riders at the event, with multiple horses across the levels.
"I have been doing a lot of work in the gym and it paid off."
However, she'll be taking it easy for the next few months as she heads to hospital this week for a hip operation which will see her off horses for three months.
The Fiber Fresh CCI1* Championship was won by Matangi's Samantha Mynott aboard CHS Ripleys Dream, with Hunua's Angela Lloyd and her gentle giant homebred horse Raucous taking out the Wairakei Resort CCN105 Championship.
The North Island took out the hotly-contested interisland Silver Spurs Teams Competition.
