"She's been going super and the bigger tracks suit her," Kennedy said. "She arrived at Bruce Herd's place on Tuesday and she's travelled and settled in nicely. She's drawn well and will be ridden off the pace a bit."
Princess Brook will be partnered by Chris Johnson, who has guided the daughter of Raise The Flag to six of her eight career wins.
"She's been getting quite a bit of weight down here," Kennedy said.
"She's the highest rated horse in the race on Saturday, but with the mare's allowance she'll carry 58.5kg and that's better than running around here with 60kg.
"When she ran third at Riccarton she was giving seven kilos to the first two horses.
