Meanwhile, his promising younger stablemate William Wallace is making good progress toward a return to racing during this month's Wellington Cup carnival at Trentham.
"He's had a few gallops and he's coming up well," Bull said. "He is still a bit green and needs more racing."
William Wallace was unplaced on debut at Waverley in the spring before the son of Darci Brahma headed south.
The four-year-old duly broke his maiden at Ashburton.
He won again on the opening day of the New Zealand Cup carnival and finished runner-up behind the impressive Margarita Mover on the closing day.
