Radford is the New Zealand No1 open-water swimmer. Robinson competed for New Zealand at last year's Commonwealth Games in Glasgow.
Rick Wells will also be involved in the coaching sessions, as he has been the previous two years. Wells swam for New Zealand for a number of years and also won a gold medal in triathlon at the 1990 Commonwealth Games.
One of the young swimmers chosen to take part is Auckland's Jack Dempsey. Jack is 9 years old and attends St Heliers School. He gained entry to the camp by winning the State Ocean Kids event in Wellington this year. He also attended the camp last year, having won the Takapuna King of the Bays kids race.
Jack has been swimming since he was 4. He can't wait to attend another camp.
"They teach us technique," he says. "We had Moss Burmester last year and he taught us butterfly, and we had Melissa Ingram and she taught us some backstroke. And Rick Wells taught us freestyle."
Jack's father, Stephen, says his son has always been an avid swimmer.
"He absolutely loves [it], loves competing. I can't keep him out of the water," he says.
Jack trains at the Parnell club and says he prefers open-water swimming to pool swimming.
"The ocean [is] a lot more challenging, and I like challenging things."
Scott Rice, the organiser of the State New Zealand Ocean Swim series, says the training camp is a great way to develop new talent.
"We're really grateful to Jetstar for making this camp possible," he says. "It's a fantastic initiative designed to nurture young swimming talent from across New Zealand.
"As a former representative swimmer I know from personal experience how important those early training years are for developing not just skills but self-confidence."
