Kahurangi National Park was suffering declining populations of native snails. In 1997 a major aerial 1080 targeting was undertaken. Pre-1080, there were 54 snails found on a 500sq m grid. One year after 1080 was applied, 147 snails were found on the same plot.

An endangered population of kaka in the Waitutu Forest, Fiordland, has been boosted by a record breeding season following a pest control operation with 1080 toxin.
In October 2010, the Department of Conservation (DOC) carried out an aerial possum control operation over 25,000 hectares of Waitutu Forest using cereal pellet baits laced with biodegradable 1080.
