All the rescuers are now off Mt Cook and safely back at Mt Cook village say Twizel Police.
The two climbers who sparked the operation were taken off mid afternoon but the rescue teams had to wait until the helicopter could get back to them.
Yvonne COOK, who was suffering from hypothermia, is being checked by a doctor but it is expected she will return to her home soon.
The last of the rescue teams was taken off by helicopter just before 5pm tonight concluding an operation delayed by bad weather.
