"The course builder did a great job. It was technical, it was within the right height specifications, and it got about the right number of clears and a hot jump off," she said.
"I was able to watch Luke (Dee) go, which was a big help, so I knew the tracks he had taken and where I could possibly shave off a little bit. The course was set out so there wasn't a whole lot of options, so it came down to accuracy and the natural speed of each horse."
McIntosh was based in Europe for 20 years and rode for Bulgaria at the 2000 Sydney Olympics, in five European championships and three world championships.
Now based in Cambridge, she particularly likes the Mills Reef setting that opens the four-day event.
"It was a lovely event and it would be good to see more occasions like that in New Zealand. It is really, really beautiful there and a lot of fun competing with so many people watching.
"Overall the organisation, courses, equipment and conditions are good and the event is right up there, if not better, with all our three star shows."
