"Bonneval is from a wonderful family and there are a lot of fillies working for that family."
She was a $150,000 Karaka yearling purchase in 2015 for Terry Jarvis, Alastair Lawrence and John Rattray.
Bonneval was placed with Cambridge trainers Murray Baker and Andrew Forsman and was a debut winner in the autumn of the following year.
Six starts later she triumphed in the group one New Zealand Oaks (2400m) and crossed the Tasman to add the group one Australian Oaks (2400m) to her record.
Bonneval won the group one Underwood Stakes (1800m) 12 months ago, but subsequently suffered a suspensory ligament injury.
Following two below-par efforts this spring, the decision was taken to retire the five-year-old.
"Mike Rennie, our newly-appointed business manager, played a big part in the purchase," Chittick said.
"Without a word of a lie, the idea was thrown out there about 1pm on Friday and three or four hours later the deal was all but done.
"Obviously, John, Terry and Alastair identified Bonneval as a yearling and they've had a great amount of fun.
"Murray and Andrew did an incredible job and now it's up to us," he said.
Bonneval will officially be in the ownership of Chittick's father Garry.
"It's great that at his age and stage he still has the passion for the game and we've got another beautiful mare in the broodmare band," Chittick said.
"These mares don't come cheaply and we are competing against international competition.
"Hopefully, the purchase will be of benefit to the New Zealand breeding industry and to us. It was great to get the deal done."
