"We went there hoping to win to confirm his place here, but he got in anyway," Marsh said. "We're super proud of the horse, he really dug deeply."
Chocante drew a wide gate and rider Craig Grylls was forced to sit three deep near the pace.
"I said to Craig to be positive and to go forward and hopefully get one off the fence," Marsh said.
A tenacious Chocante answered every call in the straight from Grylls to outstay his opposition for a brave length-and-a-quarter victory.
El Pistola, who got to the front 300m from home, took second money ahead of Jiayuguan, whose stablemate and favourite Chenille ran fifth with Megablast splitting the Tony Pike-trained pair.
"She's nominated for the City of Auckland Cup, the Wellington Cup and the Auckland Cup," El Pistola's trainer Nathan Hanley said. "She's a dead-set two miler."
Meanwhile, Shezhardtocatch downed a smart field of sprinters in the Listed Haunui Farm Counties Bowl.
Shezhardtocatch settled off the pace before she unwound powerfully in the hands of veteran jockey Grant Cooksley to get in the deciding stride on the post.
