This paper presents continuous high-resolution stable isotope records of environmental change in New Zealand from speleothems that grew over the last 31,000 yr. Oxygen isotope variation in these speleothems primarily represents changes
in the meteoric waters falling above the caves, possibly responding to latitudinal changes in the position of the Subtropical Front in the Tasman sea. Carbone isotope variations in the speleothems record changes in forest productivity, closely matching existing
