"I'm just a wee bit cautious," Prendergast said. "He's got to carry 60kgs in the really heavy going and that can take its toll but you know we can do no more than what we've done and we can't order the track conditions so we've just got to give it our best crack."
Who Dares Wins' stablemate and last start Oamaru Cup (1600m) winner Trudeau will carry seven kilograms less.
"He's come through the win really well and we're pleased with him. He's a light weight chance," Prendergast said.
"In fairness to the owners I wouldn't really lean one way or the other but in saying that if Who Dares Wins was a wee bit closer to the other horse in the weights he'd be more superior I think."
Safely through Saturday, Who Dares Wins will continue on his path toward the Gr.1 Livamol Classic (2000m) at Hastings on October 5.
"It's definitely on the cards," Prendergast said. "He's really a 2000m horse, he goes a nice mile fresh and he won the Easter Cup fresh over a mile and then won over a mile and a quarter the second day, but he does prefer 2000m."
