The Puhipuhi-Whangarei volcanic fields include Quaternary basaltic scoria cones and lava flows. These fields are south of Kaikohe-Bay of Islands volcanic field in the central part of the Northland Peninsula, within 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. Though basalts were mapped by Kear and Thompson (1964) as Holocene, later work by Smith et al. (1993) provided a range of Pleistocene K-Ar dates, including about 1 Ma for the Mirowhakitiki lavas, 260 +/- 120 ka for flows near Whangarei, and 310 +/- 150 ka for the Hurupaki cone.
