NIWA Atlas of NZ Freshwater Fishes

These pages provide an overview of the freshwater fish found in New Zealand, fact sheets for each individual species and links to other resources.

The fact sheets provide some information on each species and a map of their known, and expected (i.e. modelled) geographic distributions. Many species spend part of their life at sea and then migrate upriver, but how far they penetrate upriver  varies greatly. A plot of the known distribution relative to the distance upriver and altitude is provided to illustrate where species can be expected to occur.

To access and download information on individual species, go to the Fish Finder and select the species from the menus. If you want more information on New Zealand freshwater fish fauna, a bibliography of key publications is provided along with links to other websites that deal with New Zealand's freshwater fish fauna.
