Horeke basalts

Wairere valley

The Horeke basalts is a disused formation that contained Miocene-Pliocene basalt lava flows that covered a large area in central Northland Region of New Zealand, and in places forms a high plateau around Okaihau.

Wairere Boulders is a nature park providing walkways through boulders of basalt, derived by erosion of one of these older basalt flows that used to be included in the Horeke Basalt and are now included in the Kerikeri Volcanic Group.
