An extensive flight of late Quaternary marine terraces, in the South Taranaki region of the North Island of New Zealand, is dated using fission track, radiocarbon, and amino acid racemization methods. A simple model of terrace deformation based on a doming-type uplift pattern allows terrace strandline ages to be estimated. Twelve strandlines are recognized and are estimated to have formed during high sea-level stands at 60,000, 80,000, 100,000, 120,000–135,000, 210,000, 310,000, 340,000, 400,000, 450,000, 520,000, 600,000 and 680,000 yr B.P.
