A teenager is recovering in hospital after suffering an anaphylactic reaction to what is thought to have been sea lice, after swimming.
The 17-year-old girl, of Auckland, was at Motuihe Island yesterday when she suffered a bad reaction after being in the water.
A St John spokeswoman said emergency services were called to the scene just after 10am.
The Auckland Westpac Rescue Helicopter landed on the island, in the Hauraki Gulf, at about 10.47am.
