This chapter outlines Police expectations of how employees record incidents and near miss events, and the process for reviewing those events.

Results are now available for the second quarter (2023) of drugs in wastewater testing, which covers around 75% of New Zealand’s population.

The drugs tested for include methamphetamine, MDMA, cocaine, fentanyl, and heroin. These reports focus on methamphetamine, MDMA and cocaine as these drugs are routinely detected by the programme.

Social harm cost estimates have been included in this report. These are derived from the New Zealand Illicit Drug Harm Index 2020 (McFadden M, Bellamore L & MacDonald B. (2021). The New Zealand Illicit Drug Harm Index 2020: Research report. Wellington: Ministry of Health). The Drug Harm Index 2020 provides a conservative measure of the harms associated with the use of illicit drugs in New Zealand and considers both personal and community harms.
