At least one person has suffered burns in a reported boat fire in the Marlborough Sounds early this morning.
Emergency services - including fire crews, St John and a helicopter - are responding to an incident at Admiralty Bay, after reports of a fire on a boat.
It is understood there may have been an explosion.
A St John spokesman said just before 9am that paramedics were on the scene with a helicopter.
One person is being airlifted to Wellington Hospital. However, their condition is not yet known at this stage, he said.
