Kaikohe Hill (also Tokareireia, Memorial Hill) is a 282 m (925 ft) high hill in Northland, New Zealand with significance in Māori culture.

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. Clicking on the map enlarges it, and enables panning and mouseover of volcano name/wikilink and ages before present. Key for the volcanics that are shown with panning is: basalt (shades of brown/orange), monogenetic basalts,

undifferentiated basalts of the Tangihua Complex in Northland Allochthon,

arc basalts, arc ring basalts,

dacite,

andesite (shades of red), basaltic andesite,

rhyolite, (ignimbrite is lighter shades of violet),

and plutonic. White shading is selected caldera features.

Geography

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.

Geology

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 near by thermal Ngawha Springs and seismic studies.^[2]

Culture

The slopes of the hill contain a memorial park to Hōne Heke Ngāpua, a great-grand nephew of Hōne Heke and leader in Māori autonomy.^[3]^[4]^[5]
