Christchurch surf life-saver Matt Aplin, of North Beach, gets some air while Hayden Andrews pilots their inflatable rescue boat through surf at Warrington, near Dunedin, on Saturday.

The pair were taking part in the under-21 mass rescue event, as part of the annual BP Surf Rescue South Island Championships.

The event attracted 27 crews from 11 clubs, with Dunedin's St Kilda club the overall winner, organisers said.
