There are currently nine helicopters working to douse a 400 hectare fire which is burning through a peninsula near Kaikoura.
Fire and Emergency were alerted to the fire, which is near the Goose Flat DOC hut, on Wednesday night after trampers sent an emergency SOS signal from their radio.
"Overnight it's grown and now nine helicopters are working on the blaze, six people have been evacuated from huts and from kayaks on the river," a spokesperson said.
They said the terrain is too rough for ground crews.
