Biosecurity is an emerging issue for New Zealand. Globalisation is resulting in increased numbers of tourists and vessels visiting New Zealand each year. This increases the risk of a border incursion of a pest or disease with the potential for affecting health in New Zealand.
There are currently only a few species of exotic mosquitoes found in New Zealand that are known vectors for a notifiable infectious disease.
There were 42 interceptions of mosquitoes at the New Zealand border from July 2001 to December 2008.
The annual number of cases of notified vector-borne disease is very small, with just over 1000 cases between 1997 and 2007. The majority of these people were overseas during the incubation period, while others had previous overseas travel as a possible risk factor.
