It had a scoria cone reaching 80 metres above sea level (around 50 m higher than the surrounding land), which was quarried away.

[2] In the 2014 Treaty of Waitangi settlement between the Crown and the Ngā Mana Whenua o Tāmaki Makaurau collective of 13 Auckland iwi and hapū (also known as the Tāmaki Collective), ownership of the 14 Tūpuna Maunga of Tāmaki Makaurau / Auckland, was vested to the collective, including the volcano officially named Matukutūruru.

The legislation specified that the land be held in trust "for the common benefit of Ngā Mana Whenua o Tāmaki Makaurau and the other people of Auckland".

Auckland Council manages the Tūpuna Maunga under the direction of the TMA.
