The first race of the day, the Crombie Lockwood 1200m, was won by Sultan of Swing.
Chenille, trained by Tony Pike and ridden by Leith Innes, came in for the win in the $500,000 marquee Auckland Cup race, ahead of El Pistola and pre-race favourite Jacksstar.
In attendance was Barfoot & Thompson ambassador and Silver Fern Maria Tutaia, who spoke about her relationship with Wallabies rugby star Israel Folau.
She said the couple were "butting heads" over whether to be based in New Zealand or Australia.
"He's trying to get me over there, I'm trying to get him over here."
She said she was happy to enjoy the atmosphere rather than studiously follow the form of the horses.
"There's a few 'Harry Hardouts' here who are quite intimidating and scary."
Patrons were well behaved, with no boozy bad behaviour on display, despite the flowing beer and champagne.
One unfortunate spectator was unable to keep her balance on a viewing podium at the finish line, tumbling to the ground to the delight of her friends.
Lizzie L'amour took out the Bonecrusher New Zealand Stakes, named after the legendary racehorse of the same name.
Auckland Racing Club chief executive Cameron George said he was "stoked to get better weather this time around".
"It was wonderful to see so many people coming out to celebrate the Cup and enjoy themselves, particularly families as this really is their day."
Barfoot & Thompson managing director Peter Thompson presented the silver trophy to Pike. The silverware was commisioned by Queen Victoria in 1889, and was gifted to the Auckland Racing Club in the 1930s.
