New Zealand’s tallest mountain, Aoraki/Mt Cook has had thirty metres taken off its official height.
The new measurement comes after readings by Otago University researchers.
Currently Aoraki/Mt Cook is officially listed as 3,754 metres above sea level.
However, analysis of high accuracy GPS data has revealed that it is actually only 3,724m tall at its highest point.
Dr Sirguey, the project leader for the research, said the reason for the loss in height is probably from a massive rock-ice collapse in December 1991.
