In 2014, New Zealand announced that its drug enforcement relationship with China will be strengthened further to help identify members of organized criminal groups in China and to reduce the supply of precursors and methamphetamine from China trafficked into New Zealand. The move follows the signing of a memorandum of arrangement on precursor controls between China and New Zealand in April 2013. New Zealand has also taken action to improve regional border security through cooperation with the authorities of Fiji. In 2015, New Zealand established a training programme for the Fiji Revenue and Customs Authority and the Fiji Police Force to focus on border security by introducing drug detector dogs in Fiji. In 2015, the Fiji Revenue and Customs Authority announced that it aimed to further strengthen its partnership with both Australia and New Zealand in order to carry out joint operations and share more information about the flow of drugs in the region. In 2013, the Government of New Zealand introduced the Psychoactive Substances Act to control the importation, manufacture and sale of new psychoactive substances in the country—with interim approvals for 47 products by 150 licensed retailers.
