Abstract
Five Libocedrus bidwillii Hook. f. tree-ring chronologies were used to reconstruct‘late’ New Zealand summer (February–March) temperatures from the present to ad 1459. The reconstructed series showed that warm periods occurred around the 1470s, 1530s, 1570s, 1600s, 1730–1780, 1820–1840, 1870s, 1920–1940 and the 1960s onwards. The cooler periods were around 1630–1680, 1790–1810, 1880–1910 and 1950. The temperature reconstruction correlates significantly with others from New Zealand and to the associated part of the 1089-year temperature reconstruction from Huon pine (Lagarostrobos franklinii C.J. Quinn) in Tasmania. The general palaeotemperature trend is also similar to a temperature series derived from oxygen isotope ratios in a New Zealand speleothem, providing an example of preliminary corroboration between two different types of proxy-climate indicators.
