Battle for our Birds Matukituki 2017

Aerial 1080 operation in the East and West Branches of the Matukituki valley within Mt Aspiring National Park will start after tomorrow, on Wednesday 18th October 2017.


DOC advise that from Wednesday 18th October 2017 an aerial contractor will be aerially sowing the nontoxic “pre-feed” bait within  the East and West Branches of the Matukituki valley.  This pre-feed encourages rodents and possums to eat the pellets, which increases the effectiveness of the toxic pellets when they are sowed about one to four weeks later. 

Further updates will be issued to inform when the toxic 1080 bait will be applied.

Some important information about the non-toxic “pre-feed”:

  • The non toxic pellets are about 3 cm long, cylinder shaped and brown in colour.  They weigh about 6 grams.  The pellets are deployed at 1.5kg / ha.  The nontoxic pellets will be applied in the same areas as the toxic bait will be.  A helicopter will distribute the pellets according to predetermined flight paths controlled by GPS.
  • All tracks in the East and West Branch of the Matukituki valley will be temporary restricted while the helicopters are operating on Wednesday 18th October for up to 24 hours during the ‘pre-feed’ drop.  Immediately after the drop the tracks will be inspected by DOC staff and cleared of pellets. It is strongly recommended that people do not enter the treatment area until the tracks are cleared. 


  • In the event of weather issues the operations could continue into Thursday 19th October.  If this occurs some track closures will continue for this extra day.
