Greally said the equipment had been tested for accuracy by officers and an independent forensic laboratory. This was a critical component of the evaluation.
“Many countries, including New Zealand, have seen a rise in the number of drivers testing positive for drugs in recent years, and the direct correlation to the number of people being seriously injured or killed on our roads.
“The focus now shifts to the implementation and our processes as our staff prepare for this crucial change.”
Greally said police were working “vigorously” with other agencies and groups to clarify concerns regarding the introduction of the device and testing.
“Information about the launch and what drivers can expect will be provided over the course of the next month.”
Testing will start in Wellington next month, before scaling up from April until coverage is nationwide by mid-year.
The test will involve taking a quick tongue swab from the motorist. If it’s positive for one of the four drugs, a saliva sample will be taken for laboratory analysis. This analysis can detect up to 25 other substances as well.
A second roadside test will also be conducted. If that is positive, the motorist won’t be allowed to drive for 12 hours. If the laboratory result comes back positive, an infringement notice will be issued.
Drivers who don’t comply with the roadside drug test will also receive an infringement notice. The Government expects most drivers will be free to go about five minutes after a negative test.
