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.

The North Island's highest non-volcanic peak, Mount Hikurangi (1755 m/5758 ft), is part of this range.[3] Other prominent peaks include Maungahaumi (1213 m/3979 ft), Mount Aorangi (1272 m/4173 ft), Mount Arowhana (1440 m/4724 ft), and Mount Raukumara (1343 m/4404 ft).
