Tauanui is a 351 m (1,152 ft) high basaltic scoria cone in the Kaikohe-Bay of Islands volcanic field in New Zealand. It is the youngest volcano of the southern part of the field, having erupted around 60,000 years ago, and also the southernmost of the group. South east of the scoria cone is Lake Tauanui. To the north west of Tauanui is a smaller scoria cone, Hangunui Pā. To their north are the rhyolitic Putahi and the andersitic Tarahi volcanoes.[1]

Map
Tauanui centered in map of surface volcanics with basaltic scoria and lava fields of the Kaikohe-Bay of Islands volcanic field. Clicking on the map enlarges it, and enables panning and mouseover of volcano name/wikilink and ages before present. Key for the volcanics that are shown with panning is:   basalt (shades of brown/orange),   monogenetic basalts,
  undifferentiated basalts of the Tangihua Complex in Northland Allochthon,
  arc basalts,   arc ring basalts,
  dacite,
  andesite (shades of red),   basaltic andesite,
  rhyolite, (ignimbrite is lighter shades of violet),
and   plutonic. White shading is selected caldera features.
