The Ministry for the Environment document says 90 percent of our native seabirds and shore birds are threatened or are at risk of extinction.
Of the 32 species and subspecies threatened with extinction, 12 are nationally critical facing an extremely high risk of extinction, including species of albatross, shag, petrel, and penguin.
