Population justification: Encounter rates on Adams Island were more than three times higher than in similar habitat on Antipodes Island, where snipe coexist with mice (Miskelly 2013). Adams Island (10,119 ha) is likely to hold tens of thousands of birds, based on recorded densities of at least 4 birds/ha on other islands, while the colonising population on Campbell is likely to number in the hundreds and increasing. The total area occupied by the species is about 11,540 ha in the Auckland Islands, 2,060 ha in the Antipodes Islands, and about 3,000 ha on Campbell Island (with a total of 11,290 ha available there to colonise) (Miskelly 2013). A preliminary estimate places the total population in the band 20,000-49,999 mature individuals, but the true figure may be higher.

Trend justification: The population has ceased to decline and is increasing following predator eradication and recolonisation of Campbell Island.
