It is composed of sedimentary rock which has been thrust up in an earthquake, resulting in a characteristic flat triangular ridge having the appearance of the kind of sail regularly used by Pacific explorers such as Kupe.
On 7 March 2023, the name of the rock formation was officially gazetted as Ngā Rā-a-Kupe, following the enactment of the Ngāti Kahungunu ki Wairarapa Tāmaki nui-a-Rua Claims Settlement Act 2022.[1]
