Next out was veteran campaigner Maurice Beatson (Dannevirke) and the big-jumping Central Park. They had a cautious clear but picked up two time faults.
Daniel Webb (Hunterville) and WSJ Centaur dropped one of the bogie fences for four faults.
Fitzsimon was late to the ring because her 12-year-old gelding had lost a shoe in the warm-up, but the classy combo came in to give a masterclass.
“My plan was just for a nice steady double-clear to prepare for next week's POLi Payments World Cup Series opener,” said Fitzsimon, who hails from West Melton in the South Island.
“He was really well-behaved in there.”
The World Cup is New Zealand's top series. When Windermere Cappuccino lost the shoe, Fitzsimon contemplated not coming back for the jump-off but decided to go ahead.
“It's always good to get ring time before a World Cup,” she said.
“The course rode really well. Indoors is tight but we were lucky to have a little warm-up class in there yesterday. In that arena, everything came up quite quickly but it all rode well.”
It's the third time they've competed at the October Show for two wins and a third in the Grand Prix class.
