Mosquito Surveillance



Source: BBC

Exotic mosquitoes pose a potential threat to public health.  Mosquitoes can spread diseases to humans, transmitting Dengue Fever, Ross River Virus, Yellow Fever, Malaria, West Nile Virus, Japanese Encephalitis and Zika Virus.  Dengue, for example, is prevalent in all Pacific island nations, except New Zealand. The risk of disease-carrying mosquitoes reaching NZ increases with global warming and international travel, and more than half the world is at risk from the diseases borne by these insects.

Unwanted mosquito species are regularly intercepted at our international borders; and they enter the country via a number of pathways.  To ensure these exotics do not establish themselves in New Zealand, Health Protection staff from the Public Health Unit (PHU) maintain a mosquito surveillance programme around our ports of entry, namely Marsden Pt Refinery, Northport Log Port, Onerahi Airport, Kerikeri Airport and Opua Marina.

The Northland DHB Health Protection Unit has a well-developed strategy to provide early identification of exotic mosquitoes, and to prevent the establishment of exotic mosquito species of public health significance, in the Northland Health District.

If you have any enquiries or concern regarding mosquitoes please phone the On-call Health Protection Officer, or you can ring the toll free Mosquito Hotline number  0800 Mossie (0800 66 99 43) from anywhere in New Zealand.
