Ngangiho lava dome is one of at least 70 post-caldera lava domes erupted within the Maroa caldera, which formed sometime after about 230,000 years ago N of the Taupo caldera. The youngest of the post-caldera lava domes is Puketarata, which grew within a rhyolitic tuff ring about 14,000 years ago. The domes were erupted along a general SW-NE trend, parallel to the structural trend of the Taupo Volcanic Zone. No Holocene eruptions have occurred, but vigorous thermal activity continues.
