Police last week saw Canterbury Police District join a trial, in gaining access to Lumi to assist frontline staff with the real-time screening of suspected drug samples. Counties Manukau and Central Districts also took part in this trial.

From September 4th, results showed that Lumi has been adopted by frontline Police staff in Counties Manukau and Central Districts at 68 different events.

130 different items have been scanned and on 37 occasions Methamphetamine was identified.


Superintendent Mike Johnson, Acting Assistant Commissioner: Investigations, says the initial feedback from frontline staff who have used Lumi has been very positive.

“The results from the initial stages of the pilot are very encouraging, with dozens of incidents where our frontline officers on the streets have identified Methamphetamine through the use of Lumi.

“The real-time screening tool gives our officers confidence in knowing what they’re dealing with and is proving to be an effective tool to help our staff make better informed decisions at the scene,”  says Acting Assistant Commissioner Johnson.

ESR Forensic Research & Development Project Manager Dion Sheppard says ESR is pleased with how the Lumi pilot has started, and how these results are supporting frontline Police.

“The expansion of the Lumi pilot to Canterbury enables more Police to access the benefits of Lumi’s cutting edge technology, developed by New Zealand scientists, and supports their efforts to reduce the harm that illicit drugs cause in our communities.”

He says a new drug detection model has recently been added to the service by ESR that now allows MDMA samples to also be screened by Lumi.

“Our scientists are continuing to develop Lumi and in the past week we have expanded its capability by adding a new drug detection model to the service, enabling MDMA samples to now be screened by Lumi, alongside Methamphetamine and Cocaine.”

The MDMA model has been developed from a data set containing over 15,000 instances, and the results from the validation undertaken by ESR have determined its accuracy to be 97.7%.

The three drugs are the most common and harmful drugs in the New Zealand market.

The trial is running across Tāmaki Makarau, Central and Canterbury Police Districts over a six month period.
