Rakaumangamanga (Cape Brett Peninsula), (Māori: Rākaumangamanga) is a peninsula on the northern Te Ika a Maui (North Island) of Aotearoa New Zealand.[1] It is 15 km long.
The head of the peninsula is Rakaumangamanga (Cape Brett); a promontory which extends north into the Te moana nui a Kiwa (Pacific Ocean) at the eastern end of Pewhairangi (Bay of Islands). The Rakaumangamanga/Cape Brett Track begin's in Rawhiti, at the Opourua Bay (Oke Bay) Scenic Reserve Entrance. Sea Shuttle Bay of Islands provides a water taxi service from Opourua/Oke Bay to Maunganui Bay (Deep Water Cove) for hikers to do the track one way.
A lighthouse stands at the end of the peninsula, which rises to 360 metres at its northern end. A noted landmark, the natural arch ('Hole in the Rock') of Motukokako (Piercy Island), lies about 500 metres off the cape.
A predator proof fence across the peninsula excludes the brushtail possum, an introduced animal pest, which feeds on the pohutukawa tree to such an extent that the tree can eventually die.
The peninsula includes Opourua/Oke Bay, off Rawhiti Road, about 29 km from Kororareka (Russell, New Zealand).[2]
