The Whangarei volcanic field, named after the adjacent Whangarei Harbor, consists of Quaternary basaltic scoria cones and lava flows. The field lies in the central part of the Northland Peninsula, at the southernmost end of the Northland Intraplate Province. In addition to the younger dominantly basaltic rocks, Miocene dacitic lava domes and rhyolitic breccias are also present at Whangarei. Quaternary volcanics form a group of large cones SE of Whangarei, a NE-aligned group of scoria cones north of the city, and a group of lava flows east of the city along a major fault. The youngest basalts were mapped as Holocene (Kear and Thompson, 1964), although the age of the field is not well known and there are some indications that the latest eruption may have been during the late Pleistocene, about 30,000 years ago (Latter 1994, pers. comm.).

The Global Volcanism Program is not aware of any Holocene eruptions from Whangarei. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Whangarei page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

A group of scoria cones, one partially quarried in the foreground, lies at the NW side of the harbor city of Whangarei. The Whangarei volcanic field consists of Quaternary basaltic scoria cones and lava flows. The youngest basalts were initially mapped as Holocene, although the age of the field is not well known and could be late Pleistocene.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
