The 60-year-old, who has five crowns to his name, is believed to have become the oldest combination with the gelding to win the supreme class at the Hawke's Bay Showgrounds.
McIntosh is under no illusions the farmer and Olympian will be his usual gritty self in conditions that will test riders and mounts tomorrow from 2pm.
"Morrie, I'm sure, has been getting Gollywog ready all year," she says of the champion who has a steely resolve to pick himself up to persevere should his mount give him the heave-ho at any stage of the course, which New South Welshman John Vallance will design.
The combos will find some respite from the heat but not rain with southerlies to match.
Nevertheless, McIntosh firmly believes youngsters such as Logan Massie and Luke Dee are equally adept at stealing the limelight cometh the hour.
She highlights all the combinations will be at the mercy of Vallance.
"It'll be a very long day and it'll be hard work so we'll be hoping it'll be a good ground. We can't influence the weather so John Vallance has to look after us," she says, lauding the Orangeville-based Australian course builder as a world-class craftsman.
She is also unfazed that she has relatively inexperienced mounts in 11-year-old Estina and 10-year-old Argento.
"It's good to have experience but I've worked on them at home so I'm relying on them."
McIntosh felt the 48 field from the Lady Rider of the Year on Thursday had left Estina lethargic although she has been resting Argento.
While it suited her mount, 2014 Lady of the year champion Lucy Akers felt horses would have required a lot more stamina to keep up with the extra jumping in the scorching Bay weather.
McIntosh, who was among the four to make the jump offs on Thursday and set the pace with a faultless round in 51.84 seconds, echoed Akers' sentiments.
She felt her mares will take the next step up when she'll be jetting in three weeks to Europe where she'll base herself in Belgium with the Lake Ridge Equestrian-owned horses.
"It's pretty cool to be going back," says the daughter of Penny Stevenson, an equestrian stalwart.
Regarded as one of the most stylish and effective riders in the global arena, McIntosh thanked the stars for having such generous and understanding owners.
Estina and Argento are on the cusp of entering the realm of Grand Prix status so nurturing them will be imperative.
While it's an expensive ritual to carve a niche abroad, she hasn't got the sale of the mounts on her plan A to recoup costs, thanks to her financial backers.
McIntosh was based in Europe for 18 years, riding mostly under the Bulgarian flag.
Her resume includes a stint at the Sydney Olympics and a World Cup Final in Las Vegas, European Championships at Arnhem, Manheim, Hickstead, Donnaueschingen, and San Patrigano, World Championships at Jerez and Aachen and at Kentucky back under the Kiwi banner.
She reverted to her Kiwi nationality and relocated to her home town of Cambridge three years ago.
She reportedly owns a sport horse stable and runs her team of showjumpers and coaching business from Chestnut Glade. McIntosh is also agent for importing and exporting showjumpers.
Mentoring aspiring riders from junior to Grand Prix level in many countries is also her forte.
She started riding ponies from 7 before graduating to showhunter class until 14 when showjumping beckoned.
"I like it because it's a team sport and it doesn't come down to a judge's opinion," says the animal lover who advocates being the architect of one's own success or demise.
