The New Zealand Drug Foundation have arranged drug testing clinics in Wellington and Masterton this week after a powerful synthetic opioid was discovered over the weekend.
An investigation into the source of powdered fentanyl is under way after 12 people were hospitalised in Wairarapa over 48 hours following the drug being sold as methamphetamine or cocaine.
This is the first time powdered fentanyl has been found in New Zealand.
The Wellington clinic will run from 5pm to 7pm Wednesday at 233a Willis Street and the
Masterton clinic from 12pm to 4pm at Drugs Project Masterton, 17a Hope Street.
"This is in response to preliminary testing detecting fentanyl in white powder sold as cocaine and meth that's led to 12 hospitalisations in Wairarapa," the organisation said on Twitter.
