Moturemu Island is located in the eastern Kaipara Harbour, west of the mouth of the Hōteo River.
[3] Moturemu Island is the only known location where wild Clianthus puniceus (kōwhai ngutukākā or kakabeak) plants are known to grow.
[4] Ngā Iwi (an early Tāmaki Māori group) constructed pā on Moturemu Island.
[5] The island is an important site for Ngāti Whātua o Kaipara, due to its extensive history of occupation.
[6] Large fires in the early 20th century replaced much of the vegetation with mānuka scrub, and the island became a nesting site for introduced common starlings.
