Abstract The flora and fauna of Pupu Springs (40¡51'S, _172¡ 46'E) and five other New Zealand cold springs are described. In Pupu Springs there are 16 species of algae, 10 species of bryophytes (including three species of liverworts), and 5
species of angiospcrms. The fauna includes a phrcatic form (an eyeless planarian, Dugesia sp.), a possible glacial relict (the caddis fly Rakiura vernale), and cold stcnothcrms (e.g., the caddis fly Psilochorema tautoru). The most abundant
animals in the New Zealand springs are Mollusca, Crustacea, and' larvae of Plccoptera, Diptera, and Trichoptera.
Pupu Springs consist of five biotopes and associated biocoenoses.
