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 (14,800 ft) from the ocean floor.
The volcanic soil in the island's center is relatively fertile, so it is called "The Garden of the Islands". The makatea is honeycombed with caves, including the Vaitango Cave, Moti Cave and Motuanga Cave.
According to oral tradition, Mauke was discovered by Uke, and the island was named "Ma'uke" - "the land of Uke" - after him. Uke's descents then went on to settle Atiu. Another legend states a son of Ruatapu was murdered on Mauke, and in retaliation he killed many of the islands inhabitants. The island was dominated by Atiu, who frequently raided it. The next European to sight Mauke was John Williams of the London Missionary Society, in 1823. He left behind a Polynesian preacher, Haavi, to introduce Christianity. The third European visitor was Captain Lord Byron of HMS Blonde in 1825, who named it "Parry Island" in honour of Sir William Edward Parry. In the 1840s an Atiuian expedition attempted to raid the island again, but retreated after hearing that the Maukeans had been supplied with muskets by a European trader. In the 1860s Ngamaru Rongotini Ariki, ariki of Atiu, Mauke and Mitiaro, married Makea Takau Ariki, a Rarotongan ariki. As a result, in 1871 Mauke became part of the Kingdom of Rarotonga.
The island is subdivided into four traditional districts. Vaimutu and Makatea are not further subdivided and correspond to one tapere each. Ngatiarua and Areora districts are subdivided into 6 and 3 tapere, respectively, totalling 11 tapere for the whole island: 
Mauke's economy is primarily government-supported, with 61% of the labour force employed in the public sector. Its primary export is maire, a plant which is used to make leis. There is little tourism, with only two budget accommodation providers on the island.
Previously powered by diesel generators, since 2019 it has been powered by a 229 kW solar-diesel power station.
The volcanic origin means that the soil is rich and this is justifiably called the garden of the islands.
