The whitebaiter swept out to sea at the Rakaia River mouth last night has been named by police.
Victor Edward Boraman, 21, from Ashburton, had been whitebaiting with two friends in rough conditions when he was swept out to sea at about 7pm.
The Westpac Rescue Helicopter from Christchurch and spotters on the shore located him after he had been in the water for about an hour.
As the helicopter was attempting a rescue Mr Boraman was hit by a large wave and sucked under the water.
Weather and sea conditions were very poor and made searching difficult.
