The Tony and Lyn Prendergast-trained galloper made it back-to-back feature race wins in successive weekends by winning the 2000m feature for comeback jockey Samantha Wynne.
The victory gave Who Dares Wins and his big syndicate of owners some redemption for his second placing in the race last year.
The 6yr-old could not reel in the pacemaker, Saint Emilion, in the 2018 Canterbury Gold Cup.
This year, Wynne kept the leader, Dee And Gee, in her horse's sights by putting Who Dares Wins in the trail behind his rival.
Who Dares Wins went straight past the pacemaker in the straight before fighting off the challenge of runner-up, Residential.
"It was in the back of our minds about last year as he was beaten on the bob by Saint Emilion," Tony Prendergast said.
"It is nice to get some revenge, and he deserved this one."
The Prendergast stable produced a big training performance to have Who Dares Wins win fresh up in listed company in the Easter Cup last week.
Their effort to have the 6yr-old primed to down a quality field at group 3 level just one week later was just as impressive.
"We only gave him some light trotting and cantering, but he just thrived," Prendergast said.
"Any worries we had were put aside, and I think his fitness really showed through in the closing stages.
"He did over-race a bit early on, but once Samantha got him in a rhythm he travelled sweetly and was going away on them at the line."
Saturday's victory continued Samantha Wynne's remarkable return to the saddle from a nine-month injury lay-off.
She also made it back-to-back wins with the reinvigorated Ashburton galloper Diorissimo for trainers Sarah and Matthew Smith.
Wynne also won with Neeson for trainer Stephen McKee, before completing a winning treble with Who Dares Wins.
Beyond The Fort started a brilliant Saturday afternoon for Waverley trainer Bill Thurlow by winning the Warstep Stakes at Riccarton.
The 3yr-old cleared out to win 2000m listed feature by more than two lengths over Mohaka and Miss Valencia in an all North Island trifecta.
Just hours after his feature win, Thurlow produced his star stayer Glory Days for an excellent third placing in the Sydney Cup at Randwick.
Thurlow almost missed watching his filly win the Warstep Stakes, as he was transporting Glory Days to Randwick at the time of the race.
"We were stuck in the Sydney traffic rattling around in the back of a horse truck when the race was on at Riccarton," he said.
"Thankfully I had my wife with me, and we managed to watch the race on her phone. The vision wasn't that great but the cars around us could probably have heard us cheering as they came down the straight."
