Auckland historian and author Graeme Murdoch said Rangitoto's proposed official name meant "the day the blood of Tamatekapua was shed."
The name was traditionally linked with a fight between Tamatekapua and Hoturoa, the commanders of the Arawa and Tainui canoes respectively. Tamatekapua was injured, hence the name.
Mr Murdoch said it seemed strange to him that there was this tradition of Te Rangi-i-Tongia-a-Tamatekapua about the scrap between two men but Rangitoto also literally means "blood red sky" in relation to the eruptions.
Rangitoto's summit and peaks will be Nga Pona-toru-a-Peretu.
The Government agreed two years ago that 14 maunga - or volcanic cones - including Maungakiekie/One Tree Hill, Maungawhau/Mt Eden and Owairaka/Mt Albert, would be vested in the collective and the cones would be co-governed by a body made up of the collective, Auckland Council and Crown representatives.
The council would manage the cones.
On Maungauika/North Head Historic Reserve, the Department of Conservation will continue as manager.
