In high-risk industries, supervisors and crew leaders need to know that the people on the job are competent, current and matched to the task in front of them. Verification of competency (VOC) is one of the most practical ways to build that confidence. As we describe it on our verification of competency page, a certificate proves someone sat a course once, while verification of competency proves they can do the job today. How much weight that proof carries can depend a great deal on how well the verification itself is carried out.
We have written before about why verifying competence matters and why ongoing verification of competency belongs in every workplace. This article focuses on the practical side of verifying job competence, from agreeing the standard through to the final sign-off, so each VOC can become a genuine safeguard against workplace risk. At CheckSafe, we are a New Zealand-made competency and training management platform, built and supported here since 2022, and we keep competency records straight for some of the country's most safety-critical operations. The sections below cover each stage of a good VOC.

How CheckSafe Supports Verification in the Field
Why a Tick Box Is Only the Starting Point
A completed form shows that a check took place, although it may not always show what was checked or how the decision was reached. When the standard is loosely defined, the assessor's role is unclear or the evidence is thin, a record can look complete while offering limited assurance on site. A well-run VOC can give supervisors real assurance, meaning genuine confidence that people are competent for the work rather than simply a signature on a page.
That confidence can also support your health and safety obligations. Under regulation 9 of the Health and Safety at Work (General Risk and Workplace Management) Regulations 2016, a PCBU must ensure, so far as is reasonably practicable, that workers have adequate knowledge and experience for the work, or are adequately supervised by someone who does. The regulation also requires the supervision and training provided to be suitable and adequate, having regard to the nature of the work, the risks involved at the time and the control measures in place. From 1 April 2027, changes under the Health and Safety at Work Amendment Act 2026 mean small PCBUs, those with fewer than 20 workers, will generally need to manage critical risks rather than all risks, as WorkSafe outlines in its summary of the changes. For many organisations, a thoughtful VOC process can be one of the clearest ways to show how decisions about competency and supervision are made for each person and each task.
Setting the Standard Before the Assessment
A good verification usually begins with a shared understanding of what competent looks like for a specific task. When that standard is not written down, it is possible for two assessors on different sites to reach different conclusions about the same level of skill. Defining the competencies and assessments each role needs, and customising them to reflect how your organisation works, can help give every assessor the same benchmark. A clear standard often covers several elements.
The key steps of the task, including the critical controls that apply to it.
The plant, tools or equipment involved, along with any variations in model or attachment that may change how the task is done.
The site conditions the worker is likely to face, such as confined areas, live traffic or changing weather.
The knowledge the worker should be able to explain, including why each step matters and what to do if conditions change.
Once the standard is documented, it can become the foundation for a consistent assessment form used across teams and sites. It can also make the outcome easier to explain to the worker, who can see what was assessed and why.
Choosing the Right Person to Assess
The credibility of a VOC often depends on the person carrying it out. WorkSafe's guidance for road and roadside work on training, certifications and competency notes that checking worker competency before work begins is usually done by the site manager, or by someone the PCBU deems competent to make that assessment. In practice, an effective assessor is likely to know the task well, understand the standard and be able to judge performance fairly and consistently.
Some organisations use internal assessors for everyday tasks and external training providers for specialised plant or licensing. Either approach can work well when the evidence is kept together and held to the same standard. Bringing assessors together from time to time to compare how they apply the standard can also help keep results consistent across regions and crews.
Gathering Evidence Where the Work Happens
A VOC tends to carry more weight when it reflects the real job. Observing a worker on site, using the equipment they operate day to day and working under the conditions they normally face, can give a clearer picture of their ability than an exercise completed away from the work. Short questions during the observation can help confirm the worker understands the reasoning behind each step, which may be especially useful if something unexpected happens.
A verification will not always end with a simple yes or no. An assessment may show that a worker is ready to work independently, or that a period of supervision or a targeted refresher would be the right next step. WorkSafe's forestry guidance on training and supervision suggests choosing the level of supervision based on a worker's competence and experience. It also notes that new or inexperienced workers are likely to need supervision until they have shown they can carry out tasks unsupervised.
Recording an Outcome You Can Stand Behind
The final step is a clear, complete record. A strong VOC record typically shows who was assessed, the task and equipment involved, the assessor, the date, the evidence gathered, the outcome and when the next check is due. These details can help a supervisor make an informed decision about who takes on a task, and can help answer a request from a client, principal or auditor with confidence.
Paper forms can make this step harder when records sit in different offices or arrive back days after the assessment. Capturing the outcome digitally at the point of assessment can make records easier to find and share. In CheckSafe, every verification is recorded and time-stamped, so proof is always one click away and you can show a client, auditor or regulator exactly who was verified, and when.
Turning VOC Results Into Everyday Confidence
Individual VOC results can become more valuable once they are viewed together. When verifications are brought together in a live skills matrix, it becomes easier to see which teams are current, which assessments are coming due and where targeted training may make the greatest difference. Our recent guide on how to close competency gaps in your workplace explores this step in more detail.
Over time, good verification practice can shape how work is planned and led. Supervisors are better placed to allocate tasks with confidence, workers gain clear recognition of their skills and leaders have a more reliable view of capability across sites. In this way, verifying job competence can become part of how the business runs, supporting safer work and stronger relationships with the clients who rely on it.
Frequently Asked Questions
What Is Verification of Competency (VOC)?
Verification of competency is a practical check that confirms whether a worker can currently carry out a specific task safely and to the expected standard. It usually involves observing the worker doing the task, often alongside questions to confirm understanding, with the outcome recorded. A training certificate shows that someone completed a course, while VOC looks at their ability to do the job today.
Is VOC a Legal Requirement in New Zealand?
Regulation 9 of the Health and Safety at Work (General Risk and Workplace Management) Regulations 2016 does not prescribe a specific method such as VOC. It requires PCBUs, so far as is reasonably practicable, to ensure workers have adequate knowledge and experience for the work, or are adequately supervised. VOC is one practical way to meet and evidence that duty. Some industries, types of plant, clients or principals may also set their own requirements, so it is worth checking what applies to your work.
Who Can Carry Out a VOC?
WorkSafe's guidance for road and roadside work notes that competency checks before work begins are usually done by the site manager, or by someone the PCBU deems competent to make that assessment. In practice, this is often someone who knows the task well and can judge performance fairly against an agreed standard. Organisations may use internal assessors, external training providers or a combination of both, depending on the task.
How Often Should VOC Be Carried Out?
There is no single interval that suits every task. Organisations often set verification frequency based on the level of risk, how often the task is performed and any industry or manufacturer requirements. Changes can also prompt a check, and WorkSafe's guidance for road and roadside work notes that ongoing training may be needed when new plant or features are introduced, or when the work changes and a task needs to be done differently.
What Is the Difference Between Training and VOC?
Training is designed to build knowledge and skills, while VOC confirms whether those skills can be applied on the job. A training record shows what someone has completed, and a VOC record shows their demonstrated ability at a point in time. Used together, they can give a fuller picture of workforce competency.
Can VOC Be Completed on a Mobile Device?
Yes. With CheckSafe, managers can run and sign off assessments in the field from the mobile app, on any device and with offline functionality. Each verification is recorded and time-stamped, and the results sit alongside the worker's other evidence in one profile.
How CheckSafe Supports Verification in the Field
