# Endemic biota of the Auckland region

The Auckland region of New Zealand is home to numerous endemic flora and fauna. Many of these species have ranges restricted to the Waitākere Ranges, Great Barrier Island, Little Barrier Island and the Mokohinau Islands. A number of species have restricted ranges that include areas outside of the Auckland region, such as Buller's shearwater and Pycroft's petrel, or organisms such as the brown teal / pateke and stitchbird / hihi which have recently increased ranges due to conservation efforts.
Currently no freshwater fish species are known to be endemic to the Auckland region.
