The Tony and Lyn Prendergast-trained 7yr-old continued his brilliant association with rider Samantha Wynne when producing a late finish to win the 1600m event.
The victory brought up a hat-trick of wins in feature races for horse and rider.
Who Dares Wins and Wynne won the group 3 Canterbury Gold Cup and the listed Easter Cup before winning again at listed level on Saturday.
Wynne gave the 7yr-old a perfect run in the trail behind leader and favourite Ticket To Ride to bring up the hat-trick.
In the home straight the rider patiently sought clear air for Who Dares Wins, who powered home to win by half a neck.
Monza Circuito and Lady Style dead-heated for second, a half neck behind the winner.
Both horses were left with few excuses for defeat after carrying a massive 7kg less than Who Dares Wins.
It was weight of a different kind that was the key to the 7yr-old’s Timaru cup win, Tony Prendergast said.
"Before he had his last trial, he was about 588kg so we whittled him down to 562kg which is about his racing weight.
After receiving such a good run in the trail, Prendergast knew Wynne just had to find clear running for Who Dares Wins.
"She just had to get out from behind to get a clear run but once she got him in the clear he showed he is a smart horse."
Wynne had been unable to ride Who Dares Wins at the Grand National meeting after a knee injury that kept her out of riding for almost a year flared up again.
The jockey admitted Saturday’s victory was one of the most emotional wins of her career.
"It was great and all the owners were on course," Wynne said.
"I actually got a little bit emotional. I actually cried a little bit after the race.
"I have nearly cried before, but tears have never come out, but they were so good to me throughout my injury — the owners and the Prendergasts.
"So, it just meant a lot."
Wekaforce made up for her family’s misfortune when winning the feature sprint at the Timaru meeting.
The 4yr-old’s older sister, Morweka, was a late scratching from the listed Hazlett Stakes at Wingatui on Boxing Day after suffering an injury in the starting stalls.
Wekaforce bolted in by two lengths for trainer Terri Rae and rider Kylie Williams on Saturday.
