Post-metamorphic body growth and remarkable longevity in Archey's frog and Hamilton's frog in New Zealand

Post-metamorphic body growth and longevity of two archaic terrestrial frogs (Anura: Leiopelmatidae) endemic to New Zealand are described using data from long-term capture-recapture studies and measurements of snout-vent length. Population studies of Hamilton's frog (Leiopelma hamiltoni) on Te Pākeka/Maud Island, Marlborough Sounds, have been undertaken since 1976 and Archey's frog (L. archeyi) in the Coromandel Ranges since 1982.
