Group One producer Tavistock has died at New Zealand's Cambridge Stud aged 14, eight weeks after suffering an injury in a freak paddock accident.

Cambridge said although Tavistock had made significant progress from the initial injury, he sustained secondary complications following further surgery last week and was put down on vets advice on Saturday.

"We want to thank our vet team of Dr. Rob Hitchcock and Dr. Alanna Zantingh of Cambridge Equine along with Dr. Ric Redden from Kentucky for their extraordinary efforts to save him," the stud said.

"The Cambridge Stud staff have been nothing less than heroic in what has been an intensely difficult season for them.

"Tavistock's legacy will live on through his many sons and daughters. He cast a giant shadow at Cambridge and he will be sorely missed."

Tavistock's sons Volkstok'n'barrell, Werther, Tavago and Tarzino, have all won at Group One level.
