Marsh was all smiles as he accepted congratulations in the Ellerslie birdcage after the race.
"We think he is really high class," Marsh said.
"He was up against it today, but he travelled beautifully and won well.
"I think his potential is pretty much untapped.
"He is the coolest horse and I'm just rapt the team have given me another chance with him.
"Waikato Stud have done a super job with him as they have got him right from a couple of little problems.
"It is a big team effort and I'm proud of them."
Waikato Stud principal Mark Chittick was also delighted with the victory as he explained what it had taken to get Ardrossan back to the track.
"He had his mishaps in Australia which affected his career," Chittick said. "He came back with a few heart problems.
"Chris Phillips, our vet, has done a wonderful job with him and, although it is early days yet, he looks like he is going to get back to his best.
"He (Phillips) is an outstanding young man who left no stone unturned to find the best treatment that he could and it certainly looked like it has worked."
Chittick is keen to see the horse tested locally at Group One level before entertaining thoughts of a possible Australian return.
