Mangà Âraukawa / Lake Dive, formerly known as Lake Dive, is located in the south-east of the Egmont National Park at a height of above sea level. It was discovered in 1887 by Bradshaw Dive on his descent from the summit when he saw what he believed to be a lake. A party led by Thomas Dawson later confirmed that it was indeed a lake. In April 1964 the Lake Dive Hut was opened a short distance from the lake.
As part of the Collective Redress Act 2025, some features in Taranaki were renamed, and Lake Dive was given the dual name Mangà Âraukawa / Lake Dive. The name changes came into effect on 1 April 2025.
