Sniffing out crime – one note at a time

Customs’ detector dogs aren’t just skilled at uncovering drugs—they’re also trained to sniff out illicit cash and weapons.
Since 2013, the Reserve Bank has supplied Customs and Police with fresh and shredded banknotes to help imprint the unique scent of cash on the dogs. Despite being polymer-based, New Zealand notes carry distinct odours that dogs are trained to recognise. It’s a key tool in enforcing anti-money laundering and countering financing of terrorism laws.
Since 2018, Police and Customs—supported by the Ministry of Foreign Affairs and Trade—have jointly delivered the Pacific Detector Dog Programme (PDDP). The relationship between Customs and Police dog sections goes back 51 years.
Chief Customs Officer Dave Huff says targeting criminal finances is essential.
“Disrupting drug shipments is one part of the job. By removing the cash that funds criminal networks we are striking at the heart of their operations.
“From airports to ports, ships to storage units, our dogs continue to be an essential frontline in Customs’ efforts to keep New Zealand—and the wider Pacific—safe from transnational serious crime.”
Their success shows that when it comes to protecting our border, it pays to follow the money.
