New Zealand Mosquito Census ❘ Te Tatauranga Waeroa o Aotearoa
Citizen scientists of Aotearoa, can you help track New Zealand’s native and introduced waeroa (mosquito) species to help get a better understanding of which species live where and how they are spreading? All you have to do is catch it, freeze it and send it.

Reach: New Zealand
Nature of science focus: Online citizen science (OCS) projects can be used to develop any of the Nature of Science (NoS) substrands. Identify aspects of NoS that your students need to get better at or understand more fully, and then frame your unit to be very clear about these things when you do them.
Science capability focus: Gather and interpret data, Engage with science
Science focus: Classification, biodiversity, ecology, biosecurity
Some suggested science concepts:
Importance of tracking the health of insect populations.
Impact of introduced species on the native species of Aotearoa.
Living organisms are interconnected.
Role of mosquitoes in the ecosystem.
Many concepts could be learned – focusing on a few can often be more powerful. Develop your learning outcomes and success criteria from these concepts as well as the Nature of Science strand and the science capabilities.
Some examples of learning outcomes:
Students can:
accurately gather and log data and insects
explore the ethical issues around why some living things need to be euthanised (killed) for science research
discuss why and how we rank the animals we are working to conserve – mosquitoes are not a glamorous species, but our native species still need protecting
consider and discuss why Aotearoa has such strong biosecurity rules.
About New Zealand Mosquito Census
Aotearoa New Zealand has 13 native mosquito species and three known introduced species. Did you know that mosquitoes are incredibly important to the health of New Zealand’s ecosystem? By helping to map our country’s mosquito species, citizen scientists can play a significant role in protecting our whenua.
Mosquitoes are generally hated, but they are incredibly important to keep New Zealand’s ecosystem healthy. They are part of the food chain, and male mosquitoes are also important pollinators.
Most of our native mosquitoes in New Zealand mainly bite birds. It is only the saltpool mosquito Opifex fuscus, found on coastlines, that can bite humans as they are accustomed to mammals such as seals. All 13 native mosquitoe species have very specific habitats and living conditions, which means they are quite vulnerable to environmental changes compared to adaptable introduced species.
The three introduced mosquito species that have made their home in Aotearoa are:
striped or ankle biting mosquito (Aedes notoscriptus)
southern house or brown mosquito (Culex quinquefasciatus)
saltwater mosquito (Aedes australis).
These are the main human biters in Aotearoa, and they are now spread out and well established throughout the motu. In contrast, it is thought that our native species are possibly in decline. The lack of data means that there is not enough conclusive information about the population health of our native mosquito species.
The limited data currently available mostly comes from the biosecurity measures in place at our international airports and seaports. Mosquitoes are closely monitored at these locations so exotic mosquitoes can be detected quickly and eradicated before they can establish themselves.
New Zealand citizen scientists are being asked to send in mosquito specimens to help provide more data and so help create a clearer picture of how our native mosquito species are doing and where the introduced species have spread.
How to participate
On the Te Papa website, there is a video and simple step-by-step instructions on how to take part.
There are guidelines on:
catching mosquitoes, including in a range of environments – from your home to larvae in water
freezing mosquitoes or immersing mosquito larva in spirits
completing the mosquito census form
packaging and posting your mosquito specimen.
After you have sent in your specimen, Te Papa will reply to tell you what species you found.
Why participate
With more data, information can be gathered on whether our native species are in decline and where the introduced mosquitoes have spread. This information will also help form a clearer picture of the impact of factors such as changes in land use and climate change.
There is a chance your students could even discover a new exotic species that has slipped into New Zealand undetected!
