Maungatua, known also as Mauka Atua is a prominent ridge in the Taieri Plains in Otago, New Zealand.

[1] It rises 895 metres (2,936 ft) above the floodplain of the Taieri River, directly to the west of Dunedin's airport at Momona.

[2] The name Maungatua in Māori literally means "Hill of the Spirits",[3] and is spelt Mauka Atua by Ngāi Tahu local to the Otago Region.

[2] Carnivorous insect eating plants called sundews are found within swamps at the summit.

[6] In addition, the only naturally-occurring kāmahi in the Dunedin area are found in the southern Maungatua in Mill Creek.
