The best means for correcting Southern Hemisphere (SH) radiocarbon measurements, which are significantly influenced by temporal variations in the intcrhemisplieric offset, is by the construction of a SH-specific calibration curve from dcndrochronologically dated wood. We present here decadal ~(14)C measurements on dendrochronologically secure New Zealand kauri (Agathis australis), covering the period 195 BC-AD 995, extending the range of calibration measurements from New Zealand tree rings to more than 2 millennia.
