The former jockey had wanted to ride the mare himself in the Raetihi Cup but couldn't make the weight - he was too light.
"She had to carry nine-and-a-half stone. I was only a wee fella back then so strapped two huge bags of dirt to myself and staggered to the scales to find I was still two stone light, so I had to get another rider. But she won and that was the first winner I trained under my name," Rohloff said.
"A few years later I started with Mick Preston in Levin as an apprentice jockey and finished my time with the late Kevin Thomsen in Wanganui. Since then I've pre-trained horses, broken horses in and had a hand in winners in New Zealand and Australia, but all under other people's names, not mine. That includes with my twin brother Tony who still lives in Australia and my younger brother Warren."
On Tuesday, though, Rohloff was confident of a good run from Itsa True Story after a debut second at Trentham a few weeks earlier and a solid final gallop at the weekend.
"He was a real rogue when I first got him and everyone that knew the horse kept telling me he couldn't be ridden and would end up killing someone. I got help from the starting gate boys down in Foxton. The Rauhihi boys basically got him right for me. Back home Malcolm Wall and girls from Stephen Crutchley's stable - Heta Wiki and Crutchley's apprentice rider Mereana Hudson - helped with track gallops.
"Mereana had just returned to race riding after having a baby, so I was happy to put her on at Trentham and again at Wanganui and she rode him a treat."
Rohloff races the rising five-year-old with his wife Jill and both had grins from ear to ear after the win on Tuesday.
"What a buzz and what a ride from Mereana. She's a real talent and trainers need to see that and give her more rides. Kevin and I both have faith in the horse and we think there will be a few more stories to come yet," Jill Rohloff said.
