Zusammenfassung:An updated age calibration of the New Zealand Geological Timescale, NZGT 2015/1, is presented. This incorporates local stage reassessments and recent international chronostratigraphic calibrations. Of the 54 locally defined New Zealand stages, the basal ages of 17 have undergone changes in age of 1% or more since NZGT 2004 (three since NZGT 2012). Some intervals of Permian and Cretaceous time remain unrepresented by local New Zealand stages.
