Seven people were rescued by helicopter this morning after their four-wheel drives became stuck in an alpine river near Mount Cook.

Police were alerted to the Godley River incident in Tekapo shortly after 11am when a personal locator beacon was activated by the group.

The three four-wheel drives they'd been travelling in became stuck - two of which in the water and one on a small piece of land - as they tried to cross the river.

Thanks to the Aoraki-Mt Cook alpine rescue team, all seven were airlifted to safety, without injury.


Police said by the time the group were all safely on land, their vehicles were almost completely submerged.

Five members of the group remain at the scene as they arrange the recovery of the vehicles.
