Giant petrels Macronectes spp. are usually considered to be birds of high latitudes, breeding on islands in the Southern Ocean and (for the southern species) on the Antarctic Continent.  The most northerly breeding locality for the genus currently is Gough Island at 40° 17'S in the South Atlantic where Southern Giant Petrels M. giganteus breed.  However, individuals do from time to time wander northwards into balmier climes.

New Caledonia is a group of tropical islands a little north of the Tropic of Capricorn in the Pacific Ocean to the east of Australia.  It is a "Special Collectivity" (since 1999; previously an Overseas Territory) of France.

A record has recently come to light of a juvenile Northern Giant Petrel M. halli carrying a leg-mounted geolocator (GLS) and British Trust for Ornithology band number 1437204 that was caught near a Sperm Whale Physeter macrocephalus carcass that was grounded on a barrier reef near Cap Goulvain (165° 23'E; 21° 55'S) on Grande Terre, New Caledonia on 1 July 2010.  After being photographed the bird was released on the same day near Pointe Akaïa, close to the town of Bourail without the logger (pictured below) being removed.

The giant petrel was banded as a chick at Bird Island, South Georgia (Islas Georgias del Sur)* in the South Atlantic from where it fledged on 31 March 2010.

Both species of giant petrels, mainly juveniles, have been occasionally recorded in New Caledonia as well as in nearby Fiji and Vanuatu in the tropical Pacific (see reference list below).

Other ACAP-listed species recorded as vagrants within New Caledonian waters include Wandering Albatross Diomedea exulans, Buller's Albatross Thalassarche bulleri and Light-mantled Sooty Albatross Phoebetria palpebrata (Barré et al. 2009).
