Results of aerial application of 1080
Following the 2018 operation, the number of pest animals in the ranges was
at an all-time low, with rat and possum densities significantly reduced across the area.
When planning for the operation, estimations of rat coverage across the ranges was at 75 per cent and possum numbers had begun to increase again following the 2015 operation.
Post-operational monitoring has indicated the application was very successful. Pest species dropped dramatically, with estimated possum coverage across the ranges at 0.23 per cent and zero per cent for rats.
Species monitoring is also a strong indicator of success. Following the 2018 operation, the highest number of mature chicks since the Kokako Protection Project began was recorded from monitored pairs.
Important visitor information
Observe all information and warning signs.
Ground-based pest control will be in place on areas of parkland and some surrounding private land that wasn't treated during the aerial operation.
Always keep your dogs on a leash. This is a requirement within the park at all times.
A Controlled Area Notice is in place across the native forest area of the Hunua Ranges Regional Park and adjoining DoC-administered lands. This is to protect against kauri dieback disease.
Use hygiene stations to clean and disinfect all footwear and equipment to ensure you do not carry any visible soil into the controlled area.
In 2011 the Parliamentary Commissioner for the Environment released an independent report endorsing 1080 use.

Parliamentary Commissioner for the Environment website.
DoC also looks after large areas of parkland and uses 1080 application to manage animal pests.
For more information on the use of 1080, see the DoC website.
