We have published the latest results on exotic mosquitos established in New Zealand.

Here are the main findings:

  • At the end of 2022, three established exotic mosquito species remain in New Zealand: Aedes australis, Aedes notoscriptus and Culex quinquefasciatus.
  • The mosquito Culex sitiens was eradicated in 2020.
  • Aedes notoscriptus mosquitos have been found as far south as Timaru port as of 2022, having previously been identified only as far south as Lyttelton North in 2020.
  • If Aedes albopictus established in New Zealand, it presents a significant risk to public health as it can transmit multiple mosquito-borne diseases and survive in a wide range of temperatures.
