Abstract Global regions climatically analogous to
Auckland, New Zealand were identified by an eco-climatic assessment
model, CLIMEX, to determine possible sources of new insect pest
invasions. World distribution maps of recognised insect pest species
were used to record the presence or absence of each species within the
identified analogous regions. South-east Australia, western Europe and
the east coast of the United States are climatically very similar to
Auckland, New Zealand, and furthermore, New Zealand shares many insect
pest species with these regions. Since these regions also have close
trade and tourism links with New Zealand, any new insect incursions
recorded within these analogous climates should be of concern to
biosecurity authorities in New Zealand. Consequent risk analysis could
be more efficient at identifying potentially harmful organisms and
reduce the chances of a new pest establishing in New Zealand.
