But the favourite kicked back in the style of a potential pacing great and at the line was easily holding Titan Banner.
"That was a huge win when you consider he is only four," said Purdon, who watched the race from the outside fence of the parade ring because he is suspended.
That meant training partner Natalie Rasmussen reined the winner and Purdon admitted it was a strange feeling watching rather than being out on the track.
"But it was great to see all three of them perform to that level and when Tim [Williams, driving Heaven Rocks] attacked it made the last lap exciting. The winner is a wonderful horse but I thought the other two went great and it was good to see Heaven Rocks get around in one piece."
The win was followed by Ashley Locaz winning the last race to give the All Stars a remarkable seven winners at the premier meeting from only eight races but now their gaze turns to Australia.
Lazarus returns to racing in Perth this Friday and the following two weeks before returning to the eastern states, where Vincent will contest the A$200,000 Chariots Of Fire in Sydney on February 10. If they continue on their winning ways both will be invited to the A$750,000 Miracle Mile on February 24 and Purdon says he will not keep the pair apart.
"If they are both going well enough and win their way into the Miracle Mile then I wouldn't be scared to start them against each other," he said.
So could the new Auckland Cup winner beat the two-time New Zealand Cup winner in Lazarus?
"I think he could," says Purdon of Vincent.
"I am not saying he would but it is not impossible as Vincent is a very good horse and any horse, even Lazarus, is beatable as we saw in the early heats of the Inter Dominions.
"So that could be the first time they clash and I think if it eventuated it would be great for the industry."
Earlier, Temporale ended the argument over who is the best trotter racing in New Zealand when he outstayed Speeding Spur in the $100,000 National Trot, the second time he has beaten him this month and suggesting he has earned himself a trip to Victoria next month.
