If a New Zealand court wants to understand someone's alcohol or drug use before sentencing — or while they are on a community sentence — the answer is a drug and alcohol assessment: a clinical evaluation that produces a written report, not a laboratory result. This guide explains what a court-ordered assessment involves, which statutory powers bring one into existence, what happens at the appointment, and the line that surprises most people: courts cannot order the testing itself.
Key Takeaways
- A court-ordered drug and alcohol assessment is a clinical evaluation of use, dependency and rehabilitative needs, delivered as a written report — not an intoxication test
- Courts reach assessment through s 25 adjournments, probation pre-sentence reports under s 26, and supervision conditions under ss 49–52 of the Sentencing Act 2002
- The court cannot require testing directly: s 80ZN(2) — testing and continuous monitoring flow from a drug or alcohol condition via authorised persons under s 80ZO
- The assessment covers use history, the link to offending, mental health and risk, structured with validated instruments (AUDIT, DAST, MCMI-IV substance scales)
- Independent assessments instructed by counsel add clinical depth that a probation screening referral alone cannot offer the court
What Is a Court-Ordered Drug and Alcohol Assessment?
It is a clinical evaluation of a person's alcohol or other drug use — dependency severity, the link between use and offending, mental health context, and rehabilitative needs — prepared by a qualified assessor for a court or probation decision-maker. It is not a test for intoxication: the assessment produces a written clinical report rather than a pass or fail result.
📌 Who Commissions It
The court via a probation officer's report, a sentence condition, or defence counsel instructing an independent assessor directly before sentencing.
📌 What It Examines
Use history and patterns, dependency severity, the relationship between substance use and the offending, mental health, and treatment readiness.
📌 What It Produces
A written clinical report: severity formulation, risk and relapse indicators, and treatment recommendations the court can act on when sentencing.
Because the report speaks to rehabilitative needs in the Sentencing Act's own language, it fits directly into the material a judge reads before deciding sentence — alongside any risk material that will follow the person into parole later.
Who Can Order an Assessment — and Under What Power?
Courts reach AOD assessment through several statutory doors: adjourning sentencing so a programme or course of action can be completed, directing a probation officer's pre-sentence report, and imposing conditions once someone is on supervision. The powers are cumulative — assessment can appear at every stage from first adjournment to sentence conditions.
A court may adjourn the proceedings in respect of any offence after the offender has been found guilty or has pleaded guilty … for any 1 or more of the following purposes: … (d) to enable a rehabilitation programme or course of action to be undertaken.
The pre-sentence report is the other main doorway. When the court directs a probation officer to report under s 26, the report may include information on the factors contributing to the offence and the rehabilitative needs of the offender — the hook through which alcohol and drug issues usually enter the sentencing record. Once a person is on supervision, assessment becomes part of the sentence itself: s 49(1)(i) makes participation in a rehabilitative and reintegrative needs assessment a standard condition, and where the s 50–52 special-condition threshold is met (significant risk that standard conditions alone would not reduce), the programme the court attaches can expressly include assessment — s 51(a) defines programme to cover "any psychiatric or other counselling or assessment".
the offender must take part in a rehabilitative and reintegrative needs assessment if and when directed to do so by a probation officer.
Defence counsel can also commission an independent assessment outside those powers, usually under an adjournment so it is ready at sentencing. We prepare sentencing risk assessments and AOD reports for exactly this purpose, and they sit alongside — not instead of — the probation officer's pre-sentence report.
What Happens at the Assessment?
Referral, then consent, then the interview: the assessor explains the purpose and who will read the report before anything begins. The clinical interview explores use history and offending context, screening instruments structure the picture, and the session closes with next steps. Most assessments are completed in a single extended session, with the written report following the referral timetable.
Referral and Informed Consent
The referrer sets the questions; the assessor explains purpose, audience and limits of confidentiality before the interview starts.
Clinical Interview
An extended session covering onset and pattern of use, dependency and withdrawal history, prior treatment, and the role substances played in the offending.
Validated Screening
AUDIT, DAST and, where indicated, MCMI-IV substance scales give the formulation structure; collateral information is gathered with consent.
Report and Recommendations
The written report sets out severity, the functional link to offending, risk and relapse indicators, and treatment recommendations for the decision-maker.
The clinical core covers age of onset and pattern of use, periods of dependency and withdrawal, prior treatment, the specific role substances played in the index offending, mental health (including dual diagnosis indicators), and current circumstances — housing, whānau, employment. Validated instruments give the formulation its structure: AUDIT for alcohol, DAST for other drugs, and MCMI-IV substance-use scales where a fuller personality and clinical picture is warranted.
The report then does the work the referral asked for: it states the severity formulation, explains the functional link between use and offending, sets out risk and relapse indicators, and recommends treatment matched to need — the material a court needs if it is considering a drug or alcohol condition or a treatment-focused outcome.
Assessment vs Testing: Who Does What
This is the distinction most people miss. An assessment is a clinical evaluation that produces a report. Testing — urinalysis, breath, continuous monitoring — is compliance machinery, and the legislature has placed it firmly outside the courtroom. Courts impose a drug or alcohol condition (s 52(2)(bb): prohibiting use of a controlled drug, a psychoactive substance, or alcohol); what they cannot do is require the test itself.
The court cannot direct, indicate, or require that the offender undergo or submit to drug or alcohol testing or continuous monitoring, but the condition requires the offender to comply with all requirements arising from an authorised person giving the offender notice under section 80ZO(2).
Authorised persons — a constable, or an employee of Corrections authorised by its chief executive (s 80ZO(7)) — require testing or continuous monitoring under s 80ZO(2), including on a random basis with or without evidence of breach. The framework came in with the Sentencing (Drug and Alcohol Testing) Amendment Act 2016 and applies to supervision, intensive supervision and home detention with a drug or alcohol condition, plus post-detention and post-imprisonment conditions. Results are ring-fenced too: under s 80ZR, testing information verifies compliance and evidences breach, but cannot be used as evidence that the offender committed some other offence without consent. On the parole side, the same architecture lives in ss 74A–74C of the Parole Act 2002.
In short: we do not provide testing — testing is a Corrections and police function under statute. What an independent assessor provides is the clinical picture that tells the court whether a drug or alcohol condition, a treatment programme, or both, is the right tool. Our guide to substance use disorders in NZ parole and AOD reporting covers how that clinical material is structured.
What the Report Contains and Where It Goes
A well-built assessment report answers four questions for the decision-maker: how severe is the dependency; how does use connect to the offending; what is the current risk picture; and what treatment actually matches the need. Reports prepared for sentencing are disclosable — s 28 of the Sentencing Act 2002 governs disclosure of reports to the offender — and material going before the court should be able to withstand scrutiny in the hearing.
What a Strong Report Includes
- Severity formulation: dependency status grounded in the clinical interview and validated screening
- Functional link: the specific mechanism connecting use to the index offending — not a generic mention
- Risk and relapse indicators: triggers, patterns and protective factors in the current circumstances
- Treatment matching: the recommended intervention, intensity and sequencing the court can order or endorse
The Alcohol and Other Drug Treatment Court
New Zealand's specialist route for AOD-driven offending is the Alcohol and Other Drug Treatment Court, established as a pilot in 2012. The Ministry of Justice describes it as an evidence-based treatment pathway combining intensive monitoring, case management, drug testing and mentoring — judicially supervised treatment rather than a conventional sentence. Assessment sits at its front door: eligibility turns on a clinical evaluation of dependency, and participants move through a treatment plan under the court's ongoing oversight rather than a single-day sentencing event.
The AODT Court provides an evidence-based, best practice treatment pathway that includes intensive monitoring, case management, drug testing, and mentoring.
Case Example: From Screening Referral to Sentencing Position
Consider a typical sentencing matter (an illustrative example; details changed and combined from common patterns). A defendant pleads guilty to driving and dishonesty offending, both tied to long-running alcohol dependence. The probation pre-sentence report flags "rehabilitative needs" and recommends considering supervision with a drug or alcohol condition. Defence counsel, wanting the court to see the clinical picture rather than a flag, commissions an independent assessment under a s 25 adjournment.
The assessment documents severe alcohol dependence, links it functionally to both offence types, and recommends a structured outpatient programme with ongoing monitoring. At sentencing the judge has a treatment pathway in front of her, not just a condition name: supervision with a programme condition covering assessment and counselling (s 51(a)), an abstinence condition (s 52(2)(bb)) — and the knowledge that any testing under it belongs to authorised persons, not the court. The clinical report also becomes the baseline document if the matter reaches the Parole Board later.
