Recently users posted online feeling concerned following an upcoming 1080 poison drop in the Tararua ranges.

The operation is run by OSPRI at OSPRI’s Northern Tararua Operational Boundary & DOC (Department of Conservation) at DOC’s Tiakina Ngā Manu – Project Kākā Operational Boundary. The Proposed boundary for aerial control is still subject to consultation with no public announcement or plans for the public to see to date.

“The project is named for the iconic native parrot the kākā, plentiful on nearby Kāpiti Island and at Pūkaha Mount Bruce, and representative of the many species that are expected to become more abundant as a result of this programme.”


“Project Kākā included three treatment approaches (nil 1080, 6 yearly treatment schedule and three yearly treatment schedule and associated monitoring of target and non-target species) and began with aerial 1080 6 yearly treatment of the Hutt catchment in 2009 followed by the first of successive three-yearly treatments in 2011 covering a 29,801 ha area from Ōtaki Forks to Holdsworth campground.”

“Two further aerial operations in 2014 and 2017 have been part of the project. The 2020 operation will abut OSPRI’s Northern Tararua which is on the northern boundary of the Project Kākā operation. Most of this Northern Tararua area was previously part of DOC’s 1994–2009 treatment program,” said OSPRI in a media statement to thisuquality.

OSPRi’s Tararua Livestock and Taonga Species Protection Operation have sparked a conspiracy with many people contacting us at our website, in relation to not getting a clear answer. This was by calling multiple sources & relations involved with the drop and getting re-directed to other numbers on average six to seven times to be fortunately told that emailing OSPRI would be the best way to get any information.

Many people who have emailed thisquality tried to contact OSPRI and hadn’t received an email for any confirmation of dates for weeks. Also included were no response to their concerns in multiple emails.

One of our reporters at thisquality called up over 22 numbers in relation to the drop earlier in the week, to only be re-directed numerous times in hopes of gathering informative information about the 1080 Poison drop in the Tararuas. The numbers incl. Public health, councils, hospitals, private and corporate numbers.

On the 16th of June, 2020, thisquality understands that a response from OSPRI was sent through. Upon review, there was not any set date for the up-coming said June drop.

OSPRI’s comment in a media release to thisquality stated below:
“This operation will begin in the first suitable weather window in late winter. We are consulting with iwi and stakeholders before details of the operation are finalized.”

“Following feedback DOC and OSPRI will create an operational plan to mitigate the effects of the operation. An aerial contractor will be doing the control on behalf of OSPRI’s TBfree, and DOC’s Tiakina Ngā Manu programmes. Before the operation, the aerial contractor will contact and visit affected landowners and occupiers to discuss boundary issues, water supply safety, and the management of risks to dogs and livestock.”

“Permissions from landowners and iwi and consents from the Department of Conservation and the Ministry of Health are required for this operation.”

According to the media release, affected landowners and occupiers will be contacted again before the operation starts, to provide further details of changes in the plan due to the consultation phase and provide more information on the time frame.

“Public notices will be published in local newspapers and warning signs will be placed at all likely access points to the operational area.”

For the operation, it will begin with the distribution of non-toxic cereal pellets by helicopter.


“These brown cylindrical-shaped baits are 4cm long and 16mm wide. The toxic operation will occur one-two weeks later (weather dependent). Each bait contains 0.15% of sodium fluoroacetate and will be distributed at a 1.5-2kg/ha rate. Toxic baits are green, 16mm-20mm wide, and cylindrical shaped. Advanced GPS navigational equipment will be used to ensure the pellets are accurately placed, exclusion zones avoided and an accurate record of bait distribution obtained.”

The last control in the Northern Tararua TMA was in 2013 (Western Tararua), and 2014 in Mt Bruce to MikiMiki crown (Eastern Tararua).

“There has been no control in the central sections of this TMA since DOC’s treatment in 1996 (upper Otaki), or 2001 (Mangahao/Ruamahanga).”

According to DOC and OSPRI’s comments, health measures are very important when it comes to 1080 poison dropping.

“Warning signs will be placed at all main access points to the operational area and everyone must follow the cautions on the signs.”

OSPRI claims there’s no health risk when using this area as long as you follow the instructions.

“Do not handle any bait or allow children to wander unsupervised. Cereal baits containing 1080 are dyed green. Do not hunt or take game from within a two-kilometre radius of the operational area for human or pet consumption.”

thisquality understands that, in the media release, it states that it’s an offence to sell meat products that have been exposed to 1080. Hunting can resume approximately four months following the control work.


“Do not bring dogs into the area until the warning signs have been officially removed. Dogs are particularly susceptible to 1080. They must not be allowed access to bait or poisoned carcasses which remain toxic to dogs until they have fully decomposed.”

OSPRI and DOC state that there is no risk to public drinking water as Biodegradable 1080 is highly soluble and does not persist in water or soil. Local health authorities apply strict conditions to aerial operations so that drinking water supplies are not contaminated.

“Safety has been confirmed by tests on several thousand water samples taken after aerial 1080 operations over many years.”
