A witness said they were "taking it in turns" to provide CPR, but the man died at the scene.
Russell-Orongo Bay Holiday Park owner, Angela Armitage, said at the time that guests had returned to the park "traumatised" after witnessing the incident.
"What drew people to it was the woman screaming," she said.
"The wife was screaming so they went over, and when they realised what was happening they helped to comfort the wife.
"The wife was traumatised and so were the guests."
