Where eradication is working
Some two million invasive predators have been eliminated in a phased
and accelerating effort to rid New Zealand of the unwelcome hunters by
2050. The greatest progress has been made on islands and peninsulas.
Up next? The rest of the mainland.

Harnessing nature’s barriers
Two-thirds of New Zealand’s
nearly 500 offshore islands are
now free of invasive predators;
nature there is thriving.
Geographical barriers such as
rivers, mountains, and the ocean
help prevent reinvasion
throughout the country.
