Raukumara Range

The Raukumara Range lies north of Gisborne, near East Cape in New Zealand's North Island. It forms part of the North Island's main mountain chain, which runs north-northeast from Wellington to East Cape, and is composed primarily of Cretaceous greywacke, argillites, siltstones and sandstones.[1][2] An epoch of the New Zealand geologic time scale lasting from 95.2 to 86.5 Mya is named the Raukumara Epoch after the range.
