Sodium fluoroacetate, commonly known as 1080, is used in New Zealand to control animal pests, specifically the possum which threatens biodiversity and carries tuberculosus. Hunters fear that 1080 impacts on game animals, and some environmentalists have concerns about 1080 killing the very native fauna it is meant to save, and pollution of drinking water reservoirs with 1080 baits and poisoned animals.
DDT was used extensively for agricultural use in the 1950s and 1960s to control grass grub and porina moth. It was also used on lawns and for market gardens. Some 500 tons was being applied annually by 1959. By the 1970s its use was restricted and it was finally banned in 1989. Residues are still found in livestock and in marine mammals.
Use of the plant pesticide endosulfan was banned by the Environmental Risk Management Authority (ERMA) in December 2008, effective from 16 January 2009, after a campaign by environmental groups and the Green Party. Testing as part of the Food Residues Surveillance Programme had detected endosulfan in foods such as lettuce, strawberries and capsicum, but under 0.1 mg/kg. In June 2008 ERMA called for public submissions on the use of endosulfan after tighter controls had been placed on the pesticide in other countries. Submissions closed on 8 September 2008 and a total of 187 submissions were received. The Green Party surveyed the 85 councils in New Zealand and discovered that 18 of them had used endosulfan on sports grounds in the year preceding October 2008. They claimed that New Zealand is the only country to do so and advocated for a ban on its use.
The Auckland City Council had stopped using it in the mid 1990s. The non-approved use of endosulfan on cattle in 2007 had led to the prosecution of a farmer and the suspension of beef exports to Korea.
Methyl bromide is used as a fumigant for whole logs destined for export. There has been lobbying to stop its use due to concerns for human health.
Pesticide residues are generally low and are thought to pose no detectable threat to health.
Aerial spraying programmes
Aerial spraying of West Auckland areas was carried out by the Ministry of Agriculture and Forestry (MAF) to eliminate the invasive painted apple moth, a potential threat to the environment and economy. Foray 48B was sprayed over populated West Auckland areas for 29 months involving 48 spray events over 70 days. After the government declined to conduct a public inquiry into the spraying, a "people's inquiry" initiated by a number of academics delivered a report critical of MAF's approach to the issue.
