The lesser short-tailed bat (Mystacina t. tuberculata) has been found in 18 locations in indigenous forest in North Island since 1961, mainly in Northland kauri forest (including Little Barrier Island), on the volcanic plateau (including Tongariro National Park), Urewera National Park and in Tararua Range. In South Island this bat has only been reported once since 1961, in North West Nelson Forest Park, and must be regarded as endangered. It is present also on Codfish Island, but is thought to have become extinct on Big South Cape and Solomon Islands about 1967.
