This map was created from data available through the Marine Biosecurity Porthole (</SPAN></SPAN><A href="https://marinebiosecurity.org.nz/what-are-marine-pests/" STYLE="text-decoration:underline;"><SPAN STYLE="text-decoration:underline;"><SPAN>https://marinebiosecurity.org.nz/what-are-marine-pests/</SPAN></SPAN></A><SPAN><SPAN>), which uses information from the Port Biological Baseline Surveys (PBBS) and the National Marine High Risk Site Surveillance (NMHRSS), other verified observations are from published literature, unpublished technical reports, biosecurity databases, and records held by the Marine Invasives Taxonomic Service and research taxonomists. The PBBS were conducted from 2001 and 2007 and NMHRSS occur every 6 months. This layer includes observations of 399 non-indigenous species identified in Aotearoa New Zealand and shows areas most affected by multiple non-native species. These data were stacked by summing the number of records across all species in each cell of a 1km</SPAN></SPAN><SPAN><SPAN>2</SPAN></SPAN><SPAN><SPAN> raster grid.
