Hawke's Bay Region,North Island ,New Zealand . It is located about 20 km south-west ofHastings, New Zealand and 150 km south-east of theTaupo Volcanic Zone , close to the settlement ofTe Hauke . It is the largest lake lying within a peatland in the active tectonic Poukawa depression, between theRaukawa Range andKaokaoroa Range of centralHawke's Bay . Its maximal depth is less than one metre and its diameter is ca. 1.5 km. It was deeper in the past (about 2.5 metre) but it became articifially drained after the1931 Hawke's Bay earthquake . Lake Poukawa became a well-known paleontological site in 1956 when paleontologist Russell Price began with his excavations in thelacustrine deposits. Lake Poukawa had a species richPleistocene /Holocene waterfowl fauna. More than 13,400 anatid bones were unearthed at this site since 1956. Extinct birds found at Lake Poukawa includeBiziura delautouri ,Oxyura vantetsi ,Mergus australis ,Chenonetta finschi ,Pachyornis geranoides ,Ixobrychus novaezelandiae ,Gallinula hodgenorum ,Fulica prisca ,Malacorhynchus scarletti , andCnemiornis gracilis .12 km south of Lake Poukawa is the Te Aute swamp which is well-known for its
