Police and scientists have developed a handheld device for frontline officers to test for methamphetamine, MDMA and cocaine.
The real-time drug-screening tool allows officers to test for "the three most harmful and commonly used drugs on the New Zealand market" while "working in our communities", police said in a statement.
A six-month trial of the devices will be carried out across Auckland as well as in Canterbury and Central Police Districts.
Acting Assistant Commissioner: Investigations Mike Johnson and forensic research and development project manager for ESR - New Zealand's Crown research institute - Dion Sheppard will demonstrate the device at ESR offices in Auckland tomorrow.
