Rae said Major Tom will also head to the paddock for a freshen-up if he does impress and will be given a light preparation heading into the two-mile feature in November.
"I'll probably give him a week off [if he does head towards the New Zealand Cup]. He's a pretty clean-winded horse and he has done a fair bit of racing.
"He'll probably only have one or two lead-up races to the New Zealand Cup."
Meanwhile, earlier in the card Rae will line-up multiple stakes-winning mare Prom Queen in the Patron's Trophy (1200m).
The pint-sized chestnut is resuming after a disappointing Queensland winter campaign where she finished runner-up first-up, but was unplaced in her two subsequent runs.
"She was poorly ridden twice," Rae said.
"Craig Williams rode the horse to perfection first-up and got off the horse and told me she was good enough for Melbourne and to bring her to Melbourne."
Rae said Prom Queen will race handy from barrier three tomorrow and will then head towards the group three Lindauer Stewards' Stakes Handicap (1200m) at Riccarton in November.
"Sam Collett has had two rides on her for two wins, she knows how to ride her," Rae said.
"I want the horse ridden upfront and in the clear.
"She's a small horse, she has got to have clear running. Mentally she can cop it because she is very tough, physically with her size she can't.
"She has been good as gold in her work but I would have liked to have given her a little bit more time off, but our lease runs out in August and we want to get what we can without pushing the horse too much. She seems bright as a button. She'll either go straight into the Stewards or have one more run."
