Workplace Drug and Alcohol Screening Training

A sloppy drug test is a legal disaster. Equip your team with rigorous workplace drug testing training for oral fluid and urine collection under AS/NZS 4760:2019 and AS/NZS 4308:2023.

Aligned with the Health and Safety at Work Act 2015 and the current AS/NZS testing standards, IMPAC's Workplace Drug Testing pathway — delivered in partnership with our NZQA-approved sub-contractor InScience — equips HR managers, H&S leaders, and designated collectors with the medicolegal discipline required to execute valid oral fluid and urine drug screening.

Category overview

When your organisation's drug testing process relies on guesswork or a "she'll be right" mentality, your entire Drug and Alcohol Policy is legally void. A broken chain of custody, a missed integrity check, or a misinterpreted screening result instantly destroys the validity of the test — exposing the business to unfair dismissal claims, or worse, allowing an impaired worker straight back onto a high-risk site.

Across our Workplace Drug Testing pathway — delivered in partnership with our NZQA-approved sub-contractor InScience — we reject the casual approach to specimen collection. Driven by the realities of employment law and site safety, our trainers demand absolute operational discipline.

Whether your team is conducting Oral Fluid Collection or Urine Drug Screening, we focus on the medicolegal requirements that govern the process: securely preparing donors, performing on-site integrity testing to catch tampering and adulteration, and processing specimens for accredited laboratory confirmation without leaving a single legal loophole.

Key Focus Areas

What this training covers

Uncompromising chain of custody

Learn the non-negotiable procedures for documenting, sealing, and dispatching specimens. Eliminate the procedural gaps that lawyers use to invalidate tests.

Integrity testing and tamper detection

Dismantle the tricks used to beat the test. Master on-site quality control to confidently detect sample adulteration, dilution, or substitution before the specimen ever leaves the site.

Strict donor preparation

Navigate the highly sensitive process of preparing a donor for collection — ensuring absolute privacy, respect, and legal compliance to protect both the worker and the organisation.

Interpreting results and laboratory dispatch

Move past the initial screen. Accurately interpret on-site results, communicate potential outcomes, and correctly process specimens for accredited laboratory confirmation.

Working with New Zealand's legal framework

Applicable Safety Regulations in New Zealand

Medicolegal testing demands strict compliance. Our training ensures your organisation confidently executes screening against these critical, up-to-date standards:

AS/NZS 4760:2019 — The joint Australian/New Zealand standard for the procedure for specimen collection and the detection and quantitation of drugs in oral fluid.
AS/NZS 4308:2023 — The joint Australian/New Zealand standard for procedures for specimen collection and the detection and quantitation of drugs of abuse in urine.
Health and Safety at Work Act 2015 (HSWA) — The primary legislation dictating the absolute duty to ensure the health and safety of workers, including managing the severe risks associated with impairment on the job.
Drug & Alcohol Policy Documentation — Legally defensible policy frameworks, consent forms, and chain-of-custody records that survive employment dispute scrutiny.

NZQA Unit Standards

Our Workplace Drug Testing courses are delivered in partnership with our NZQA-approved sub-contractor InScience and align with the unit standards covering oral fluid collection and urine collection competence.

Who Should Enrol

Industries and Roles

Designated Specimen Collectors

Personnel explicitly tasked with performing on-site oral or urine screening who need the technical qualification to collect, test, and dispatch samples without compromising integrity.

HR Managers and Advisors

Human Resources professionals responsible for managing, implementing, and enforcing the company's Drug and Alcohol Policy, ensuring all procedures are legally defensible.

Health & Safety Managers

Leaders who oversee high-risk operational environments and need to ensure that the testing programmes keeping impaired workers off the site are rigorous and compliant.

Operational Supervisors

Frontline leaders who manage qualified personnel or services, requiring a deep understanding of the testing process to ensure standards are maintained on the floor.

FAQs

Frequently asked questions

Workplace drug testing is a medicolegal process that can result in the termination of employment. If a collector makes a mistake with the paperwork, uses expired testing kits, or breaks the chain of custody, the result cannot be trusted. In an employment dispute, a flawed process means the test result is thrown out, leaving the company completely exposed.

Oral fluid (saliva) testing generally detects very recent drug use and is excellent for identifying immediate impairment. Urine testing typically detects historical use over a longer window of time. Both methods have specific legal standards (AS/NZS 4760:2019 and AS/NZS 4308:2023) and require distinct, rigorous collection procedures to avoid tampering.

You prevent cheating by utilising highly trained collectors who understand integrity testing. Our courses teach personnel exactly what to look for — from checking the temperature and specific gravity of urine to identifying adulterants — ensuring that donors cannot manipulate the results.
