The Queensland winter carnival is an option, although targets there have yet to be seriously looked at.
"I am a little bit mindful of the preparation he has already had, he's been up for a while and I will be guided by his next two runs," Carston said. "Queensland is still definitely on the table, he's won at 1200m to a mile so he's pretty versatile, and we'll see what happens."
Hasabro will carry 61kg on Saturday, having already won twice this campaign under 60kg, and goes into the race off the back of a strong effort for fourth in the Group 1 Otaki WFA Classic (1600m).
"He just missed away and he ended up in the worst part of the track, but his run had plenty of merit and we were very happy," Carston said. "We brought him home for a freshen-up with 10 or 12 days in the paddock with these two races in mind."
The stable will also be represented in the Easter Cup by Pullyoursocksup, who finished sixth at her most recent appearance in the South Island Breeders' Stakes (1600m).
"She definitely deserves her place in the field and could do with a shower or two of rain, but she gets in on the minimum and has a good barrier and that helps a lot," Carston said. "If she was to run in the top three then the bit of black-type would be perfect for her. Her last run was good on a firm track from a wide gate."
