Violence Risk Assessment in New Zealand

When a court, the NZ Parole Board or Corrections must make a decision about someone with a history of violence, the question is never simply "is this person risky?" — it is what the risk is, what drives it, how it has changed, and what would manage it. A violence risk assessment answers those questions with evidence rather than impression. At Precision AOD Solutions, assessments are prepared by psychologists registered with the New Zealand Psychologists Board, working with qualified AOD clinicians — a combination that matters, because substance use sits behind a large share of violent offending.

What Is a Violence Risk Assessment?

A violence risk assessment is a structured forensic evaluation of the likelihood, nature and severity of future violence, together with the conditions that increase or reduce it. It draws on multiple sources of evidence — offending history, clinical interview, records and collateral information — and applies validated instruments and structured professional judgement so the conclusion is transparent and testable.

The output is not a single number. A defensible formulation sets out the risk level, the scenarios in which harm is most likely, the factors driving it (including alcohol and other drug use), the protective factors present, and a management plan that decision-makers can apply — release conditions, treatment targets and supervision priorities.

When Is One Ordered?

• Sentencing courts: where the Crown or defence needs an independent view of future risk and rehabilitative options before sentence is imposed
• The NZ Parole Board: risk assessments inform the undue-risk test under the Parole Act 2002 for release decisions
• Corrections: risk management planning, programme placement and reclassification decisions
• Community safety matters: where agencies need an evidence-based view of risk for supervision and support planning

How the Assessment Works

Every assessment follows the same structured method, regardless of whether interviews are conducted in person or by secure Audio-Visual Link:

1. Records review: summaries of facts, sentencing notes, incident and misconduct records, prior assessments and clinical history establish the baseline before any interview begins.
2. Structured interview: clinical interviews examine offending history, substance use, triggers, treatment engagement and current functioning.
3. Collateral information: with consent, whānau, treatment providers and corrections staff contribute information that corroborates or qualifies the interview account.
4. Validated instruments: actuarial and dynamic tools are scored and integrated — see below for the instruments we use.
5. Formulation & report: findings are written into risk level, scenarios and a management plan, answering the specific questions set out in the instruction.

A step-by-step walkthrough of the interview and documentation process appears in our guide to forensic psychological assessment for parole.

Structured Tools We Use

Validated instruments and structured professional judgement underpin every formulation

Most risk statements in the New Zealand market go uninstrumented. Our formulations name the tools behind them:

• Violence Risk Scale (VRS): a dynamic instrument that captures static history and changeable drivers of violence, tracks treatment-related change across its domains, and stages readiness — making it directly actionable for courts and the Board.
• RoC*RoI: New Zealand Corrections' actuarial estimate of reconviction and reimprisonment risk, normed on local offender data — the baseline screen every Corrections file carries.
• SAPROF: structured assessment of protective factors, so strengths are documented with the same rigour as risk.

Instrument selection depends on the referral question and offending history. Our explainer of risk assessment instruments used by NZ Corrections sets out how these tools differ and how courts read them.

What the Report Contains

Each report is written by the psychologist who conducted the assessment and structured so a decision-maker can apply it directly:

• Referral question and methodology: the instruction answered, the sources reviewed and the instruments applied
• Risk formulation: level, nature and scenarios of expected violence, including the role of alcohol and other drug factors
• Dynamic and protective factors: what can change, what has changed through treatment, and what supports desistance
• Management plan: conditions, treatment targets and supervision priorities tied to the findings

For sentencing matters the findings integrate with sentencing risk assessment evidence; for release matters they align with the Section 21 framework described on our parole risk assessment page.

Fees & Instructing a Violence Risk Assessment

Most court-directed risk assessments are funded through Legal Aid. Funding is contingent on individual circumstances, and we cannot guarantee there will be no cost to the client, as Legal Aid can seek to recover costs in the future — but we facilitate the application end to end, and approval typically takes 3–4 weeks. Private and counsel-commissioned assessments are quoted by complexity.

To instruct us, provide the legal context (court or Board, charges, hearing date), the questions the report must answer, and available records. We confirm conflicts, timeline and funding pathway before assessment begins. For parole matters, refer six months ahead of the hearing; for sentencing, six to eight weeks before the sentencing date.
