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. 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, is part of this range. Other prominent peaks include Maungahaumi, Mount Aorangi, Mount Arowhana, and Mount Raukumara.
