The search for a missing skydiver in Lake Wakatipu is on hold while the police get more equipment.
Californian Tyler Nii, 27, is presumed dead, after he plunged into the lake during a tandem skydive last week.
His instructor was pulled from the lake with minor bruises.
The area Mr Nii crashed into is thought to be about 250 metres deep and the Police Dive Squad has been searching the lake using sonar equipment.
