Description	Radiocarbon dating of deposits from a sequence of terraces at Ballantrae Research Station, near Woodville, provides the first dates for alluvial deposits of Ohakean age to the east of the southern Ruahine Range. Here these terraces have been vertically offset by the active trace of the Wellington Fault. To the west of the trace, upthrown aggradational deposits are dated at c. 13 000 yr B. P. To the east of the trace, younger aggradational deposits dated at c. 10 500 yr B. P. have inundated and buried the downthrown older terrace surfaces. Vertical offsets and rates of offset were calculated for the Ohakean terrace surfaces along this section of the Wellington Fault. Scarp heights range from 19 m to 10 m. Minimum rates of vertical offset vary from 1.23 mm/yr to 0.76 mm/yr.
