Eradication programmes for Southern Saltmarsh Mosquito (SSM) eradication have been funded by Government since 1998. From the initial site in the Hawke's Bay eradication efforts have been expanded to include other North Island sites where the mosquito was discovered.
After the discovery of SSM in areas around the Wairau Estuary and at Lake Grassmere at the top of the South Island in 2004, the Ministry of Health commissioned a report on the potential pathways of entry for mosquitoes into New Zealand.
The scope of the report included a literature review of the spread of mosquitoes globally, and of work done on pathways of such spread; an analysis of the historical spread of mosquitoes in New Zealand; a consideration of the mosquito exclusion measures in place; identification of all possible pathways of entry and spread of SSM and a description of those scenarios considered most likely; and recommendations of further measures that could be imposed to exclude/contain mosquitoes, and SSM in particular, based on the most likely scenarios of entry and spread.
