Kaikohe-Bay of Islands volcanic field
The Kaikohe-Bay of Islands volcanic field is in the Northland Region of New Zealand. Eruptions have occurred over the last 10 million years. All the cones older than 2 million years have eroded away, leaving plateaus from Okaihau to Kerikeri and north to Whangaroa. In the southern part of the field, around 12 small basaltic scoria cones, and a rhyolite dome erupted in the last 500,000 years around Kaikohe. The field is considered dormant, rather than extinct.[1]
