Abstract
Reconstructions of temperature and zonal and meridional flow over New Zealand are presented for the period back to AD 1731. The reconstructi ons have made use of ring-width chronologies from five endemic species (three different genera); the first time multispecies reconstructions have been attempted in New Zealand. The chronologies were standardize d using techniques that attempted to maintain as much of the low-frequ ency variance in the tree-ring series as possible, so that long-term c limatic trends could be detected. In independent periods verification, the reconstructions of temperature explain between 30 and 33 per cent of the variance, whereas zonal and meridional flow reconstructions ex plain 31-43 per cent and 18-39 per cent of the variance, respectively.
