There are about 68,000 kiwi left. Kiwi populations are declining by about 2% per year in areas where predators are uncontrolled – that's about 20 per week.
​
DOC uses aerial 1080 to protect kiwi from introduced predators in areas from Fiordland to the Coromandel Peninsula.

In Kahurangi National Park after aerial 1080 operations in 2014 and 2016 duckling numbers increased to 65 and 40 in those years compared to less than 25 where there was no predator control.
​
Results from monitoring at Kahurangi are outlined below.
