The population is primarily in coastal settlements such as Tryphena, the largest settlement in Tryphena Harbour, at the southern end.
Other communities are Okupu, Whangaparapara, Port Fitzroy, Claris and Kaitoke.
There is no central power, and houses require their own generators.
There is also extensive use of solar water heating, solar panels for electricity and wind-powered generators.

The population swells substantially during the main holiday seasons, though it is still not a major tourist destination due to its relative remoteness.

From the end of February 2007, the island was seen around the world as the setting for the BBC One reality show Castaway, which was filmed there for three months.
