There have been numerous other places named "Motukaraka" throughout New Zealand, including in the Auckland suburb of Green Bay, and in the Hokianga Harbour.

The island is composed of Waitemata sandstone, which formed between one and two million years ago as a section of a river valley.

[1] Historian Percy Smith records that in the late 18th century Motukaraka Island was a heavily fortified pā of about 100 members of the tribe Ngāti Pāoa.
