Kaikohe Hill centered in map of surface volcanics with basaltic scoria and lava fields (brown) of the Kaikohe-Bay of Islands volcanic field. To its north is the violet shaded rhyolitic deposits of Putahi and red shaded andesite of Tarahi.

Kaikohe Hill (also Tokareireia, Memorial Hill) is a 282 m (925 ft) high hill in Northland, New Zealand with significance in Māori culture.
Geology
It is on the western edge of the town of Kaikohe. To its north east are the extinct volcanic cones of Putahi and Tarahi and Lake Ōmāpere.
It is a basaltic scoria cone in the southern part of the Kaikohe-Bay of Islands volcanic field.[1] The geological basement to the nearby volcanoes is likely to be the Permian-Mesozoic Waipapa Group argillite at perhaps more than 1,736 ft (529 m) deep as defined by drill hole at the nearby thermal Ngawha Springs and seismic studies.[2]
