The guardians of the area around Mount Tongariro say Wednesday's eruption shows the mountain's warrior status, and makes the people of Ngati Tuwharetoa happy see the maunga come alive.
The eruption happened at about 1.30pm in Te Maari crater, the same place where a big eruption happened in August.
A spokesperson for Te Runanganui o Ngati Hikairo ki Tongariro, Te Ngaehe Wanikau, says the mountain looked spectacular with steam and sulphur billowing out.
He says the mountain is showing his mana, and whanau at its base aren't concerned.
Mr Wanikau says a rahui, or a protective restriction on the track from Red Crater to State Highway 46 remains in place following the last eruption.
