New Zealand swimming administrator Bill Matson died suddenly yesterday, on his 72nd birthday.
A statement from Fina, the world governing body for swimming, said Matson's death followed surgery he underwent during the last days of the world championships in Shanghai, China, which finished on July 31.
Swimming New Zealand chairman Murray Coulter said Matson's sudden death came as a shock.
"We had all expectwed he would make a speedy recovery from his surgery. It's an absolute tragedy for the family and for the sport of swimming in Wellington, in New Zealand and around the world," Coulter said.
Matson had been involved in swimming administration for over 40 years, and was a former president and life member of Swimming New Zealand. He also served on the New Zealand Olympic Committee board.
