New Zealand outlying islands

The New Zealand outlying islands comprise nine offshore island groups, located in the subtropics and subantarctic, which are part of New Zealand but lie outside the territorial sea off its mainland coast (except the Solander Islands). Although considered to be integral parts of New Zealand, seven of the nine island groups are not part of any region or district, but are instead designated as Area Outside Territorial Authority. The two exceptions are the Chatham Islands, which form a special territorial authority (island council) themselves, and the Solander Islands, which are part of the Southland Region and Southland District.

Eight island groups sit on the New Zealand continental shelf, which forms a part of Zealandia. The Kermadec Islands, northeast of mainland New Zealand, are on a ridge, whose location as part or not part of Zealandia is not yet proven by geologists.[1][2] Both sources show a map drawn of Zealandia, marking the location of islands north and south of New Zealand.

The term is also used sometimes to further encompass the Balleny Islands, a group of sub-Antarctic islands technically considered a part of the Ross Dependency and covered by the Antarctic Treaty.

The five island groups of the New Zealand Subantarctic Islands, including their territorial seas, are a World Heritage Site.

Population

The islands are all uninhabited except the Chatham Islands.

There is a staffed meteorological station on Raoul Island of the Kermadec Islands. The meteorological station on Campbell Island has been unstaffed and automated since 1995. There was a meteorological station on the Auckland Islands from 1942 to 1945. The Three Kings Islands and the Auckland Islands were formerly inhabited. There have been failed settlement attempts on Raoul Island, the Antipodes Islands and the Auckland Islands. The Solander Islands have never been inhabited except by shipwrecked sailors or marooned stowaways (for the longest period, from 1808 to 1813 by five European stowaways).

Several elevated bathymetric features north of Zealandia are possible candidates for Zealandia prolongations or separate microcontinents (Fig. 2). These include the Three Kings, Lau-Colville, and Tonga-Kermadec ridges and Fiji, which are known Cenozoic volcanic arcs (Graham, 2015), and the Mellish Rise and Louisiade and West Torres plateaus. However, no continental basement rocks have yet been sampled from any of these features, so their continental nature remains unproven.{{cite journal}}: CS1 maint: date format (link)
