Auckland, New Zealand's largest city, is constructed over the 600 km2 Auckland Volcanic Field. The field contains more than 50 maars, tuff rings, and scoria cones that were formed during eruptions over the past 193,000 years. Only one volcano was formed during the Holocene. About 620-570 years ago, two phases of eruptive activity formed a low shield volcano capped by a scoria cone at Rangitoto.
