Pollen diagrams are described for 2 sites near Cape Regina from far N North Island. Forest persisted throughout the last 17 000 yr and while initially containing cooler elements change indicating a maximum in diversity and complexity was attained between 10 000-6800 BP. This was the warmest and probably most mesic environment represented in the record. Nothofagus was never an important element and Dacrydium cupressinum, Podocarpus spp. and tree ferns dominated throughout. Agathis australis expanded from c11 500 BP but declined after 3000 BP, perhaps associated with increased droughtiness. Shrubland also occurred throughout the record; natural fire was an important component in their function. Fire incidence increased in the recent past suggesting it was an agent in forest destruction following human occupance
