“Private lands, which often have numerous owners, are being targeted for 1080 drops by Ospri, DOC and regional councils. A local area, Mahakirau, with 20 partners, “agreed” to poisoning on the strength of a single signature and a bribe of $10,000. At Kennedy’s Bay a group of land parcels with hundreds of different Maori owners, is to receive a 1080 drop on the say-so of just two members of the community. The lack of consultation in both operations has caused enormous friction in the particular communities. In the case of Tataraakina only one trustee gave consent for their lands to be poisoned. How much longer will these authorities be allowed to get away with this behaviour?”
by John Veysey of Coromandel At present there are eighteen bovine TB-infected herds in Hawkes Bay. Ospri has found a TB-infected pig on private land. The infected pig was taken from the 12,000 ha of Tataraakina C trust land. Ospri tells farmers that this find “confirms that the spread of TB in Hawkes Bay is coming through wild life and not through movement of livestock”. BUT Ospri seems to have no logical explanation of how TB gets into a wild pig. They tell farmers that the pig can not transfer the disease to another pig nor to another animal. Ospri’s supposition is that the possum transfers the disease to cattle but for the possum to get the disease from the pig it must eat the meat from a dead pig which has died from the infection. OSPRI Failure For decades Ospri and its predecessor, TB-Free NZ, have failed to establish how possums gain infection from cattle or how the disease is transferred back again from the possum to the cow. Ospri’s idea of transfer from a pig depends on a “carnivorous” possum. Eh?
“The Department of Conservation has been giving Pirongia landowners a flier that says “1080 does not kill or harm fish.” This is completely misleading and dangerous for those who eat fish, eels, shellfish and koura. See for yourself what scientists have said in an independent summary of research into 1080 and fish. Quotes: “There are indications of sub-lethal effects on fish among the very limited studies that have been done:“significantly greater weight loss occurred in eels exposed to 1080 compared to those that were not”…”the sub-lethal concentrations of 1080 in the water may have been sufficient to inhibit eel metabolism”…”sub-lethal 1080 exposure presented to eels through ingestion of contaminated possum may have been sufficient to temporarily inhibit eel metabolism” (Lyver et al., 2005) “96-hour [exposure of Rainbow trout, half of individuals dead at] 54 mg/l, sub-lethal effects on survivors – not specified” (ERMA Agency, Appendix C)”Fish & Game ranger Lawson Davey said the national safety limit of 1080 in any food was 0.001 milligrams per kilogram, but the Cawthron Institute’s October toxicology results of 22 trout fed the poison showed muscle tissue with 1080 levels up to 4.7mg per kg. https://i.stuff.co.nz/national/64310400/1080-drop-raises-trout-risk-fears Preliminary results of a DoC-commissioned study by the Cawthron Research Institute has shown the flesh of trout that ate mice containing the toxin would have levels of 1080 that exceeded New Zealand Food Safety Authority limits. https://www.nzherald.co.nz/nz/news/article.cfm?c_id=1&objectid=11332357 The maximum concentrations measured in trout tissue (up to 4.7 mg/kg) were observed at 24 h and 48 h after ingestion. The concentration decreased to close to 2 mg/kg after 84 h. An increase in 1080 concentration in the flesh was observed after 120 h, but the number of replicates at this interval was low (n = 2).

1080science.co.nz Is 1080 Harmless to Fish? | 1080 Science The Parliamentary Commissioner for the Environment’s report on 1080 poison (Wright, 2011) claimed that effects of 1080 on populations of eels, koura and bullies had been studied (by Suren & Lambert, 2006) and that no effect on any of the fish was found.
Ex Horowhenua Mayor Michael Feyen speaks about the alternatives proposed by the Advance NZ party that will create job opportunities for the people. (Currently the associated dollars funnel into the 1080 poison state owned gravy train). Michael has always been supportive of alternatives to 1080, during his time as both councilor and mayor with the Horowhenua District Council. Unfortunately it was not a vision shared by enough of his colleagues to have gained any traction. Time for change. EWR
WET JACKET PENINSULAS, FIORDLAND, AERIAL 1080 POISON DROP STARTS – WEEP FOR THE KEA!
By Carol Sawyer
“So, here they are again and this time DoC have done a wee conjuring trick and say it is for stoats (there being no rats). Stoats don’t eat 1080 baits.”
“We have an estimated 1,000 Kea left in the wild in New Zealand….. in the whole world in fact, as they are endemic – i.e.they exist only here! The latest 1080 poison drop in the Matukituki Valley, Mt Aspiring National Park, February 2020, killed 50% of the Kea. More than that will die in the Wet Jacket Peninsulas drop because it is midwinter and the Kea are very hungry.”
Do you know what happens to 1080-poisoned Kea? They stagger around taking hours and hours to die. They bury their heads in the snow to try and get relief from the pain. Dr.Jo Pollard says “The keas’ deaths will be horrific, with extreme muscular spasms going on for many hours.” David Attenborough called them the most intelligent bird in the world. They are the world’s only alpine parrot.
Three BK-117 helicopters – ZK-IME (a.k.a Big Red the Rescue Helicopter), ZK-HJK,(white), and ZK-HEM, (red and white), and a Longranger, all belonging to HeliOtago Ltd, left Dunedin at 6.30 pm this evening heading west to be in place for starting their evil work tomorrow morning. Seven choppers arrived at Monowai tonight… yet to find out if they are all HeliOtago Ltd or if three are from another company. I have been told HeliOtago Ltd flew the prefeed baits from a private farm property at Monowai, last weekend.
This area has never before been poisoned. The drop was planned for last October but there were NO rats so it was postponed and, I am told, the poison that had been brought south for the drop was instead used in the Kepler Mountains drop last March, which was squeezed in just before lockdown…. I’m informed they added on the Princess Mountains to use all the extra poison up. No monitoring done there apparently.
So, here they are again and this time DoC have done a wee conjuring trick and say it is for stoats (there being no rats). Stoats don’t eat 1080 baits.
I can tell you what it WILL kill in large numbers… Kea. As the area has never before been poisoned there are many Kea reported to be in the area. (A while back a pilot sent me a photo of seven Kea that landed beside him when he touched down there.)
We have an estimated 1,000 Kea left in the wild in New Zealand….. in the whole world in fact, as they are endemic – i.e.they exist only here! The latest 1080 poison drop in the Matukituki Valley, Mt Aspiring National Park, February 2020, killed 50% of the Kea. More than that will die in the Wet Jacket Peninsulas drop because it is midwinter and the Kea are very hungry.
The Empire of the Dept of Conservation, greedy helicopter companies, and all their parasitic acolytes WILL fall… but it will be too late for the Kea.
Any of you gutless DoC employees reading this who put your personal livelihoods before your knowledge of this travesty and the horror it entails, and keep your mouths shut pleading “I can’t afford to lose my job”… hang your heads in shame why don’t you! You know who you are!
Ditto the local media who know about this drop and are too scared to touch it and tell the truth. You know who you are too.

Dear Mr Shadie
Re: Government poisoning of World Heritage sites in New Zealand – Open letter
I am writing to bring your attention to the serious issue of the New Zealand Government’s aerial poisoning of a World Heritage site and hope that you will urgently contact the World Heritage Committee so they may act on this matter. The 40,000 ha Wet Jacket area is to be aerially poisoned this month under contract to the government’s Department of Conservation (DoC). This poisoning is not justified as the appropriate scientific or technical measure necessary for the conservation of this site, and would breach New Zealand’s obligations under the World Heritage Convention.
The contractor’s application to DoC (attached) to poison the Wet Jacket area describes a hotspot of biodiversity, home to at least 17 species of endangered birds as well as 25 other species of birds. Six species of lizard have been recorded including the rare Fiordland skink. The invertebrate fauna is described as “not fully explored” and “distinctive and important” (Contract Wild Animal Control, 2019).
The 1080 poison to be used is broad spectrum, affecting organisms that breathe oxygen (ERMA, 2007). It is added to cereal food baits and distributed from hoppers carried beneath helicopters. The distribution process creates fragments (Morgan et al. 2015) and dust (Wright et al., 2002). Native lizards, birds and invertebrates are all known to feed on the cereal bait (ERMA 2007). The poison is highly toxic, readily contaminates despite stringent precautions, travels rapidly in water and up food chains, causes reproductive defects across a vast range of species and has highly variable effects which remain poorly understood, with studies being sparse and of poor quality (ERMA, 2007).
Due to poor monitoring, effects of 1080 poisoning on populations of most NZ native animals are unknown (ERMA, 2007; Whiting-O’Keefe & Whiting-O’Keefe, 2007). Only six species of birds were reported as reliably monitored through 1080 drops. Of those, fernbirds suffered most with an estimated 9% loss of the local population per poisoning (Fairweather et al., 2015). Kea have also been intensively monitored, with the finding that on average 12% of birds are killed per operation (DoC, 2016).
The Application to poison the Wet Jacket area shows significant shortcomings, as follow.
The reason given for poisoning the Wet Jacket area is to “protect the health and integrity of the flora and fauna susceptible to predation by rats, stoats and possums.” It lists animal species it considers particularly in need of protection: bats, kiwi, parakeets, kea and fiordland crested penguins.
These claims of susceptibility are not referenced or supported by scientific observations. In fact, it was concluded twice that predation was not a problem to kea (Jackson, 1969; Elliot & Kemp, 1999). Short-tailed bats were considered relatively safe from predators, being fast and agile, fiercely mobbing intruders and choosing winter roosts that were inaccessible (Lloyd et al., 2005). “Evidence” of predation of long tailed bats was just an observed association between low bat survival and high rat numbers (Pryde et al 2005; O’Donnell et al., 2011). Doc has attributed failures of some of its invasively monitored bird nests to predators, however they are not representative of undisturbed nests (Ellenberg et al., 2015).
Known costs left out of the Application include negative ecological effects from aerial poisoning. In many cases, rat numbers rebound to vast new heights within months (Innes et al., 1995; 2010; Powlesland et al., 1999; Ruscoe et al. 2008; Sweetapple et al., 2006). This effect can decimate prey such as invertebrates (Sweetapple & Nugent, 2007). Re-poisoning of rats is likely to become less and less effective due to the rats learning and developing physical tolerance (Byrom et al., 2013; Mitel, 2016; Pollard, 2016). Thus the Eglinton Valley (also in World Heritage site Fiordland National Park) has just received its fourth aerial poisoning in five years (2014, 2016, 2019, 2020). Despite increasing the intensity of the poisoning for rats in September 2019 (DoC, 2019a) another poisoning was carried out this May.
Mouse numbers usually increase soon after aerial poisoning (Innes et al., 1995; Sweetapple & Nugent, 2007, Ruscoe et al., 2008). The increases in rodents during the months after poisoning create ideal conditions to for stoats to flourish (Byrom et al., 2013). In addition, stoats that survived aerial poisoning were found to switch from eating rats to eating native birds (Murphy et al., 1988).
The Application contains no discussion of the conservation importance of the loss of kea, with previous studies indicating a 12% loss of local birds is expected. DoC claims that kea in remote areas are unlikely to get poisoned, however 9% of marked birds were killed by 1080 in an area chosen by DoC to represent remoteness (Kemp et al., 2016 unpublished). The total number of wild kea left is unknown and possibly less than 1000 ((Bond & Diamond, 1992; Harper, 2012; Roy, 2016).
Issues not addressed
Important issues left out of the Application include how much bait will enter the marine area; what effects there will be of baits, fragments and dust in the littoral zone (e.g. on penguins) and in the productive areas of shallow, still water; what will the effects be of the predicted “zero grazing ungulates” (being the last large grazing animals left); what are the chances of cold weather killing off rats in winter if they are left unpoisoned; should a highly diverse, unexplored ecological community be poisoned to try to make it better; what will be done if pest animal numbers are low, without poisoning.
DoC has a strong track record in misleading, pro-poisoning behaviour. It intrudes on nesting birds, attaches equipment to them and their nests, blames predators for nesting failures, then uses the poor nesting results to justify predator control (e.g. for kea (Kemp et al., 2014, unpublished), mohua (Elliott 1996), kiwi (Waterworth, 2019) and kaka (Moorhouse et al., 2003)). It quotes increased “nesting success” as an indication of a bird population’s positive response to poisoning, but nesting success is likely to increase if a population is culled (Nilsson 1984; Arcese & Smith 1988). “Five minute bird counts” are used by DoC to assess bird numbers. This method is notoriously unreliable (Westbrooke & Powlesland 2005; ERMA 2007; Green & Pryde 2012; Hartley 2012), due to major problems such as bird calls increasing after poisoning as birds try to find their dead partners and family, or search for new company.
DoC’s pro-poisoning bias and lack of scientific honesty are also apparent in its publications. For example a stoat plague that followed DoC’s aerial poisoning at Okarito (Kemp et al., 2015, unpublished) was truncated from the published graph (Kemp et al., 2017), despite this being an important outcome. In another example, in a study on bats after a 1080 operation, the contents of one bat roost tree had spilled onto open ground. Inspection revealed a baby bat with placenta attached, which tested positive for 1080. Other roosts in the study were inspected for dead and dying bats by roost camera “where practical” (Edmonds & Pryde, 2015). The published paper has a re-worded section of the original report that now insinuates all roosts were searched equally for dead babies (Edmonds et al., 2017).
The claim that some Eglinton Valley birds are prospering due to DoC’s 1080 poisoning (Minister of Conservation’s media release 11/4/20) is impossible to make: poison in bait stations and trapping are used to try to control mammals in the Eglinton Valley and any separate effects of 1080 cannot be assessed. Mohua (including some from the Wet Jacket area) were restocked there in 2010, 2015 and 2017.
Due to low rodent densities the Wet Jacket area poisoning was postponed in October 2019 (DoC, 2019c). The poisoning has since been promoted in the media as being needed to kill stoats, on the unscientific basis that local, heavily monitored kiwi chicks haven’t been surviving (Waterworth, 2020). These locally monitored kiwi weren’t even mentioned in the Application. There may be a very low stoat kill rate if there is a lack of poisoned rats for them to eat. If the poisoning proceeds regardless of low pest numbers, this will not be unusual. Makarora was poisoned in 2017 for rats despite low numbers (data accessed 22/3/17 via Official Information Act request); poisoning of Arthurs Pass in 2019 went ahead with no rats (data accessed 8/10/19) (mice were present but 1080 pellets are not usually eaten by mice (Fisher & Airey, 2009).
A fraction of the resources being used to poison the Wet Jacket area could support careful, scientific studies of the biodiversity and ecology of the area before a management plan is decided upon. Where populations of rare organisms are considered in immediate danger, localised, benign management can be applied, such as tree banding and caging, and protecting nesting kiwi and kea from DoC staff.
I trust you will act to prevent the unfounded wholesale poisoning of this precious site.

How could I have been so wrong?! I seriously thought a pandemic and its ensuing economic chaos would put an end to aerial 1080 poison. I thought the government might have a last blast but this is something else. Jacinda’s Labour Government has turned 1080 poisoning and trapping into a make-work scheme. The only income this scheme makes is from the TAXPAYER!!!
I think the only thing that will end aerial 1080 poison and this mad desire to kill everything introduced into our forests will be nuclear war.

Did he see the writing on the wall? Below is a letter I wrote to him a month ago.
May 28, 2020 is the anniversary of the explosion in the Bromley, Christchurch, warehouse leased by PCR Ltd, where PCR Ltd/Kiwicare Corp Ltd was illegally making pure 1080… without a resource consent… inside a shipping container!! The building remains so contaminated that the Fire Service will not allow their officers to enter if there is a fire… yet there is no warning signage on this building in a VERY public place, surrounded by other businesses and next to a privately owned aquatic centre.
Work Safe NZ said it would take them a year to complete their investigations. We await their findings with bated breath. The West Coast Regional Council, (49% owner of the 1080 bait factory) has invested over $2 million of their ratepayers’ money in this factory. There are only 10,000 ratepayers. The building remains highly contaminated and dangerous. Even if the WCRC has public liability insurance, that will not protect them when criminal activities have taken place. I do hope that insurance company has woken up!
The whole story, for anyone who has not seen it, is in the links below. This has all been hidden behind a veil of silence… from FENZ, ESR, Work Safe NZ, Environment Canterbury, Christchurch City Council, West Coast regional Council, Dept of Conservation, and PCR Ltd itself. The media have not touched it.
Meanwhile, Michael Meehan is scampering off to another well-paid job … before the investigation results are announced.
I sent this letter below to him nearly a month ago. I copied in all West Coast Regional councillors. No-one responded or even acknowledged receipt, not even Michael Meehan who was the addressee, but I have since spoken to a councillor and so I know they all received it.
“Apr 21, 2020, 8:11 PM
Dear Michael Meehan,
Below is a story that was posted on social media on 21 March, 2020. I would be interested to hear your comments please.
I understand from the real estate agent who arranged the lease on Unit 1, 56 Wickham St, Bromley that it is leased on a month by month basis and, as it would appear it has still not been decontaminated and still contains toxic chemicals, obviously it can not be used. I gather the lease is $21,995 per annum plus GST, which presumably means PCR Ltd has paid out over $22,000 in the past 11 months for an unused building.
What steps has Pest Control Research Ltd taken to start the decontamination process and why are there no hazardous chemical warning signs on the building?
It appears the other tenants have NOT been notified of this state of affairs. Unit 2 was leased out relatively recently to a painter (flammable materials next door, in other words) and I’m told he was not made aware of the situation with regard to Unit 1.
The owner of the joinery business, in Unit 3, was also unaware of the true situation.
I’m told Unit 4 is occupied by XXXXXXX, the son of the building’s owner. I do not know whether he knows the true situation or not.
Do you, in your role as CEO of the 49% shareholder, the West Coast Regional Council, and as a Director of Pest Control Research Ltd, feel you have a duty of care to these innocent people ?
I did a short followup story the other day, as I was sent photos of the Bromley warehouse taken on 17 April, 2020 which made it obvious that still nothing has been done about this building. Link here:
I wonder if all the Councillors are aware just how deadly this stuff is ?
Let’s just take the sodium monofluoroacetate (1080). This is the 100% pure form manufactured without resource consent at Bromley, (not the 0.15% contained in a 1080 bait):
Based on fatal or near-fatal cases of human poisonings, the dangerous dose (LD50) for humans is 0.5-2.0 mg per kg of bodyweight. (Negherbon 1959).
This means that just 35 mg can kill a 70 kg person. That means that ONE STANDARD (5 GM) TEASPOON OF PURE 1080 CAN KILL 70 x 70KG PEOPLE …..and make another 70 people very ill. (The LD50 is the dose required to kill 50% of people who ingest it. It doesn’t mean the other 50% get off scot free!)
Anyway, I would be grateful if you could answer the above two questions about decontamination and duty of care and I am interested in your comments on the Bromley situation. My interest in this is that I am appalled that such a dangerously contaminated building, one that even fire officers are forbidden to enter, has sat there for nearly a year without the neighbours (immediate and otherwise) being informed of the dangers, and with no warning signage on the building at all.
