Distribution
World: Circumpolar, widely distributed throughout the northern and southern hemispheres in high latitudes, including the Arctic and the sub-Antarctic.
New Zealand: Snares, Antipodes, Auckland, Campbell and Macquarie Islands, Taiaroa Head (Otago Peninsula) and possibly Stewart Island, are localities that represent breeding populations of the tick, whereas records from Dargaville, Whangarei, Peka Peka, Waikanae, Lower Hutt, Palliser Bay, Wellington, near Haast, and Southland are from birds that are likely to be outside their breeding range.
