Abstract: The Lower Taieri Plain lies close to sea level in a tectonic basin separated from the coast by a range of hills uplifted along the Titri Fault System. The basin is infilled with dominantly fluviatile sediments at least 150 m and possibly up to 300 m thick. Coastal range uplift rates in the past 100 ka are no more than 0.2 mm/y, and a similar rate of basin subsidence is likely. A 35 m deep buried channel on the uplifted side of the Titri Fault System is attributed to eustatic lowstand fluvial incision. The channel was drowned and the basin flooded by mid-Holocene marine incursion. Eustatic change has been a strong influence on basin stratigraphy. Lowstand incision may have the potential to erode previous highstand sediments, unless they are entrapped by uplift events on the Titri Fault System. (auth)
