John van Leeuwen
From OpenwaterpediaFoveaux Strait on 7 February 1963 in 13 hours 40 minutes. A member of the Oreti Surf Life Saving Club, van Leeuwen was inspired to swim the strait by Barrie Devenport who was the first man to swim Cook Strait a few months earlier.
 Foveaux Strait
Foveaux Strait is a 16-mile strait that separates Stewart Island/Rakiura, New Zealand's third largest island, from the South Island. The strait is a rough and often treacherous stretch of water. The strait is about 130 km long (from Ruapuke Island to Little Solander Island), and it widens (from 14 km at Ruapuke Island to 50 km at Te Waewae Bay) and deepens (from 20 to 120 m) from east to west.
