Tarahi andesite (red shading), and nearly basaltic scoria and lava fields (brown) of the Kaikohe-Bay of Islands volcanic field in centre of map. To its immediate south east is Putahi rhyolite (violet) and to its north Te Ahuahu andesite (red) separated by the basalt (brown) of Haruru pā. 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.
