The long finger on the western coast of the main island has several small islands located close to its tip. The largest of these, Alert Stack, is located to the south of the peninsula and separated from it by a narrow channel. The peninsula points almost directly towards the Western Chain, a line of stacks located some 4 kilometres to the southwest of the main island. These islets are simply named Tahi, Rua, Toru, Wha, and Rima, the Māori words for the numerals one to five. Between this chain and North East island lies the small stack of Vancouver Rock.
