Part of the Nga-pu-Toru, it is 277 km northeast of Rarotonga. Mauke is a raised coral atoll, with a central volcanic plateau surrounded by a jagged fossilised coral makatea which extends up to one mile inland. A narrow layer of swamps lies between the makatea and the plateau. The entire island is surrounded by a fringing reef, pierced by six passages, and sits atop an extinct volcano rising 4,500 m from the ocean floor.
