"If that race gets off the ground, he may go there, and then he would have open class options like the Flying Stakes or Kaikoura Cup to get ready for the NZ Cup," said Purdon.
While Purdon doesn't need to commit to an IRT New Zealand Cup start yet.
Akuta's chances of going to the iconic race must have increased with Sunday's win and his presence in the market has created a rare X-factor.
The possibility he could start in age group races on the way to the Cup increases the disparate form lines heading into the race, with other favourites Self Assured and Spankem still yet to start their campaigns, although they both trialled well last Wednesday.
Possible northern Cup contenders Old Town Road and Kango will start in the Spring Cup at Alexandra Park on Friday night, while defending champion Copy That put his defence back on track when he won at Melton in Victoria on Saturday night.
He will contest the Victoria Cup there on October 8 before returning to Addington, adding yet another form line to the Cup build-up.
But one of Australia's best pacers who finished well behind Copy That on Saturday, Lochinvar Art, is out of the NZ Cup after he was stood down for 28 days for an internal bleed, which will see him either retired back to stud or exported to North America.
Copy That's trainer Ray Green has confirmed if last year's Cup-winning driver Blair Orange chooses Krug over the likely one-off engagement for Copy That this year, his regular northern driver Maurice McKendry will be offered the Cup drive.
