Vaccination assessment tool

Update: After a review of public health advice and the release of updated guidance to businesses, the vaccination assessment tool has been removed.

If your business or workplace isn’t covered by a government mandate for COVID-19 vaccination, you can choose to do a risk assessment to see if you can require work to be carried out by vaccinated workers.

Vaccination assessment tool removed

Vaccination assessment tool removed

The Government has removed the Vaccination Assessment Tool, which had been in place under the COVID-19 Public Health Response (Vaccination Assessment Tool) Regulations 2021.

The COVID-19 Public Health Response (Vaccination Assessment Tool) Regulations 2021 were formally revoked on 12 May 2022. 

As the tool has been revoked, businesses should no longer use it for health and safety risk assessments. The information on this webpage, that was previously available for the tool, is only published for archival purposes. 

For businesses that have validly undertaken a health and safety risk assessment using the vaccination assessment tool, any employment decisions (such as terminating the employment of unvaccinated workers) that have already been made based on this assessment stand.

Employers may still be able to maintain vaccination requirements, however these requirements would need to be supported by a full work health and safety risk assessment. The circumstances where vaccination could be required are likely to be more limited than they have in the past.

Any employer currently involved in an employment process based on a vaccination requirement that was put in place using the vaccination assessment tool is recommended to pause that process. The employer should then undertake a full work health and safety risk assessment to take in to account the current public health advice before proceeding with any further employment processes.

Previous guidance on the Vaccination Assessment Tool is below. This is available for reference only as the tool was removed on 12 May 2022.

Carrying out a risk assessment

To do this, your business can either:

  • do a health and safety risk assessment using a method you consider fit-for-purpose for your business (including following existing industry guidance), or
  • use the vaccination assessment tool.

It’s up to you to decide what tool you use – businesses have sole discretion to make this decision.

Vaccines are an excellent tool to reduce the risk of COVID-19, but this doesn’t replace all other controls businesses should consider.

Even where a business has implemented a worker vaccination requirement, they will still need to consider whether any further measures should be implemented to minimise the risk of COVID-19 at work including complying with other Government requirements.

Previous risk assessments

In light of recent public health advice you may need to do a new assessment. Guidance will be available soon from WorkSafe.

Vaccination assessment tool

Factor Lower risk Higher risk
Does the worker work in an indoor space that is less than 100m2? No Yes
Is it unreasonable for the worker to maintain physical distancing of 1 metre from other people? No Yes
Is the worker in close proximity to any other person for more than 15 minutes? No Yes
Does the worker provide services to people who are vulnerable to COVID-19? No Yes

How the vaccination assessment tool works

The vaccination assessment tool consists of four factors. You will need to answer ‘yes’ to at least three factors before it would be reasonable to require vaccination for workers who carry out that work.

When applying the tool to a particular role or job, you need to think about all of the tasks involved in that role, including those that aren't performed on a daily basis.

If a worker doesn’t want to be vaccinated, but the tool indicates it is reasonable to require vaccination for their work, or part of their role, then you must comply with your employment law obligations, eg act in good faith and consider any reasonable alternative employment arrangements or redeployment, or other measures that may minimise risk.

Workers covered by the tool

The tool can be applied to anyone who would be considered a ‘worker’ under the Health and Safety at Work Act which would include a contractor and any volunteer who is considered to be a ‘volunteer worker’ under that Act.

Engaging with workers

You need to consult with your workers and their representatives when applying the tool and also about any other appropriate alternative COVID-19 control measures.

You might find that consultation with workers highlights other measures that could minimise risk, or alternative working arrangements, that mean the higher risk factors in the tool may no longer be met, ie that a ‘yes’ answer becomes a ‘no’ answer.

Even if you decide not to use the vaccination assessment tool and use an alternative health and safety risk assessment, you’ll need to consult with workers, under the Health and Safety at Work Act.

Exempting workers

You can exempt any workers from a vaccination requirement you introduce if you think you are still able to appropriately manage the health and safety of workers and others. For example, if you have workers who can’t be vaccinated for medical reasons you might exempt them.

The tool’s outcome

When you use the tool, you’ll get an outcome, telling you if work should be carried out by a vaccinated worker or not. You don’t have to implement the tool’s outcome, but if you decide not to, you have to be prepared to justify your decision.

You must consider the following in the situation where the tool has provided a ‘yes’ outcome, but you do not want to require vaccination:

  • whether there are any other measures that could reasonably be used to minimise the risk associated with unvaccinated workers doing the work,
  • the outcomes of consultation on the application of the vaccination assessment tool and control measures, and
  • any other factors you consider relevant.

Not meeting the threshold to require vaccination

If your work does not meet at least three ’yes’ factors and you decide not to require vaccination, you should still consider whether any measures should be implemented to minimise the risk of COVID-19 at work. You will also need to comply with other Government requirements.

Dealing with third parties that require vaccination

Even if your health and safety risk assessment finds that vaccination isn’t required on health and safety grounds, you might deal with another business or third-party that makes vaccination a condition of doing business with them, or accessing their premises.

You are entitled to make business decisions and to structure your business to meet your clients’ requirements but you need to be able to justify these requirements and should consider seeking legal or health and safety advice.

If an entry requirement applies to your workers, you may choose to discuss with the owner or manager whether it is still required, in light of the updated public health advice.

Where the owner or manager does not change their requirements, you can continue to require vaccination for workers who need to regularly attend those premises in order for you to keep doing business with them.

Before doing this you must make efforts to consider who you send to those premises and whether it is possible to reorganise tasks or the business so that only those workers who are vaccinated are required to attend the premises.

If this isn’t possible, you may need to carry out a workplace change process, which could lead to redundancies.

Challenges to the vaccination assessment tool outcomes

Businesses must engage with workers and their representatives when applying the vaccination assessment tool.

Given how clear and specific the factors in the vaccination assessment tool are, businesses who apply the tool in accordance with the regulations should have confidence that their decision is justifiable.

Usual employment law and processes continue to apply. Employers should take care to be fair and reasonable in their employment decisions and work in good faith with employees and unions before deciding on any employment outcomes.

Employees will be able to bring a personal grievance if they feel they have been unjustifiably dismissed or disadvantaged as a result of a decision their employer has made about vaccination.

Employers and employees can access support from MBIE’s employment early resolution service or mediation service to resolve employment problems. Should mediation not resolve the dispute, the Employment Relations Authority or Employment Court can determine the issue.

WorkSafe inspectors will take an education-first approach, they:

  • can help businesses understand what you must do to meet COVID-19 legislation requirements
  • can give businesses the chance to make changes and ‘do the right thing’, and
  • may take enforcement action if those changes aren’t made.

How do I apply the factors in the tool?

Environment factor

What is the definition of an internal area?

An internal area means an area within a workplace that, when all its doors, windows, and other closeable openings are closed, is completely or substantially enclosed by—

  • a ceiling, roof, or similar overhead surface; and
  • walls, sides, screens, or other similar surfaces; and
  • those closeable openings.

How do I calculate the size of an area I work in?

  • You can use a measuring device or pace out the space to get an estimate of how big it is.
  • Alternatively, you could ask the property owner of your business premises for relevant documentation to specify the size of your indoor space.

What if I work outside?

If you work outside then you will be at lower risk, ie you will get a ‘no’ answer.

If I meet with colleagues in smaller meeting rooms, does this count when assessing the environment factor?

Yes. When applying the tool, a business will need to consider all aspects of a person’s work.

Physical distancing factor

What is meant by being able to maintain physical distancing from other people?

  • In some workplaces it can be considered reasonable for workers to maintain physical distancing of 1 metre even if they do not always choose to do so. In this situation, the lower risk indicator would apply, ie the answer would be ‘no’.
  • In other workplaces, it may not be reasonable for workers to maintain physical distancing of 1 metre and workers may have no choice but to be in closer proximity (ie less than 1 metre) with other people from time to time. In this situation, the higher risk indicator would apply, ie the answer would be ‘yes’.

Time factor

What if I do come within close proximity of another person during the day but it’s for less than 15 minutes?

  • Under this factor, close proximity is defined as being within a metre of another person when carrying out work.
  • The indicator relates to contact with any one person continuously for 15 minutes, so if someone spent more than 15 minutes alongside someone else then they would meet the threshold. It is not cumulative for working in close proximity with a number of people over a day.
  • This factor applies each time you interact with another person.

Vulnerability factor

What does “vulnerable to COVID-19” mean?

In the tool the factor relating to people who are vulnerable to COVID-19 is defined as workers who provide services to people who are:

  • under the minimum age to be vaccinated;
  • exempt from being vaccinated under a COVID-19 order (for example being medically exempt from being vaccinated); or
  • at risk of severe illness from COVID-19.

The Unite Against COVID-19 website has a section that sets out who is at higher risk of severe illness if they contract COVID-19 and the definition of vulnerable people is based on this definition.

How do I know if people are vulnerable to COVID-19?

  • A business will need to determine whether any of their workers provide services to other people who the business considers are vulnerable to COVID-19.
  • A worker who provides a service in a public-facing job may be more likely to come into contact with people who are vulnerable to COVID-19. However, this needs to be assessed on a case-by-case basis.
  • This factor applies where there are in-person interactions with members of the public (not including your co-workers).
