Te Toiokawharu, along with the entire Waitākere Ranges area, is within the traditional
rohe of the
Te Kawerau ā Maki iwi. The hill, alongside an adjacent peak, were known to Te Kawerau ā Maki people as Ngā Puketūrua, or the hills of burrows. The hill was recognised as the highest point of the Waitākere Ranges in the early 1940s, when city waterworks engineer AD Mead located and measured the height of Te Toiokawharu. The hill had not previously been surveyed, due to its isolation and unsuitability for a
trig station location. The name Te Toiokawharu, "The Peak of Kawharu", references the giant
Waikato Tainui warrior
Kāwharu, who together with
Ngāti Whātua attacked the Waitākere Ranges settlements in the late 17th century. The peak was the location of a hollow tree, where hunters would wait to ensnare
kererū. The name was chosen by Wiremu Paora and Rangitutahi of Ngāti Whātua in the 1941, descendants of Kāwharu who were consulted by the New Zealand Geographical Board. The hill's traditional name, Puketūrua, was not known by the board at this point. ==Recreation==
