External Health and Safety Expert Review
Stats NZ’s COVID-19 Health and Safety Risk Assessment
1. Introduction
ACT
Stats NZ Team Leader – Health, Safety & Wellbeing, People & Culture, Elmie Botha requested Jeena
Murphy, Prof NZISM, from Working Wise Ltd to undertake a review on their COVID-19 Health and
Safety Risk Assessment as an external health and safety expert.
The brief was to verify Stats NZ’s Risk Assessment and logic against the:
• MOH guidelines
INFORMATION
• Public Health Act 2020 with its two orders for Vaccination and Testing
• Public Service Commission Guidance
• WorkSafe NZ guidance on risk assessment
• Other relevant legislation and guidance.
OFFICIAL
The brief also included commenting on whether risk assessment was fit for purpose to present to
Stats NZ Legal and the PSA Union as a case to state that the activities outlined in the risk assessment
THE
create health and safety risks in relation to Covid 19 and employees do need mandatory vaccinations
and testing.

2. Risk Assessment
RELEASED
Overall, the risk assessment methodology is sound in the light of the announcement for businesses
to use a risk assessment model to assess risks for business mandated vaccinations related to roles.
In the absence of the COVID-19 Protection Framework announced by Minister for Workplace
Relations and Safety Michael Wood, workplaces are directed to WorkSafe NZ Guidance and risk
assessment process, that focuses on how to decide what work requires a vaccinated employee.
On 26 October the Government announced that a new risk assessment process will be
introduced under public health legislation later this year. This guidance helps employers
make a risk assessment under HSWA in the interim and provides our interim enforcement
approach. WorkSafe NZ: 27 October 2021
2.1 Role vs Task
The WorkSafe NZ guidance states:
Your focus in the risk assessment must be on the role – the work being done
– rather than the individual performing the role.
A concern is in both the
ELT Memo (draft V1 and V2) and the
Covid combined census field risk
assessment (EXCEL) the Statistics NZ risk assessment clearly states it is assessing risk for task and
1

activity, as opposed to role. This could easily be aligned to WorkSafe NZ’s focus on role by stating
that the tasks are related to field roles and census roles (or appropriate terminology).
2.2 WorkSafe NZ Risk assessment questions not addressed
ACT
These are the risk factors that WorkSafe NZ recommend are considered for during the risk
assessment. Currently they are not clearly addressed. At the end of the
ELT Memo (draft v2) document on Page 11, there is a list of roles. The factors below should be considered for each of
these roles.
On the
Covid combined census field risk assessment (EXCEL), comments on some of these factors but
not in a structured way.
INFORMATION
My concern is the COVID-19 risk assessment does not clearly address these questions which are the
basis of the risk assessment at present.
They do need to be addressed as all Government information points back to WorkSafe NZ to provide
OFFICIAL
guidance on how to do this work-related health and safety risk assessment, until the Public Health
Legislation is updated.
THE
A recommendation is adding into the
ELT Memo (draft V1 and V2) a section
entitled WorkSafe NZ
Risk Assessment Considerations after the intervention logic section.
Consider these risk factors

3. The Risk Assessment Methodology
3.1. Vaccination as control measure in current state – no guarantee everyone vaccinated
The risk assessment methodology used by Statistics New Zealand is robust and offers a useful
framework for assessing risk.
INFORMATION
One question mark is the use of vaccination as a control which is included in the assessment to
establish ‘residual risk’. It seems this control is assuming that all staff are vaccinated, which may or
may not be the case. Perhaps it would be better to have the control as
‘vaccinations – not all staff
could be vaccinated, so it may not be a fully protective control.
OFFICIAL
Then the additional controls would be: THE
• All relevant staff fully vaccinated.
• Additional Covid 19 testing.
UNDER
The risk setting may be different between the inherent risk and residual risk – eg. I would think it
would be higher as there’s no way to determine if the current vaccination protocols will work as not
everyone can be vaccinated.
This risk assessment would make a more compelling case for mandatory vaccination. In this case the
initial residual risk is 16, and the final risk control effectiveness is 8, considering workplace mandated

vaccination and Covid testing.

4. General COVID-19 Control Robustness
The controls outlined in the risk assessment are in line with the advice provided from Ministry of
ACT
Health to prevent the spread of COVID-19. None of the control details were provided for further
comment.
4.1. Stats NZ Intervention Logic – from Covid Combined Field Risk Assessment
My comments – in blue
Wording from Stats NZ risk assessment in italics
INFORMATION
It’s a good methodology categorising the tasks across field and census have been categorised into
Indoors and Outdoors. All of these tasks require interaction with the wider community.
It is a sound assessment that the consequence in these cases remains at severe as the environment is
OFFICIAL
largely beyond our control and an outbreak would affect both organisation and the community at
large.
THE
There is good logic, and the assessment is consistent with what is known about the efficacy of
vaccinations.
With the initial controls in place and added vaccination the following assumptions:
UNDER
•
It reduces the rate of transmission, so the impact becomes lower. In effect the vaccination is
a form of PPE and reducing the impact therefore in the cases of interaction with public we
have moved the consequence to major.
•
The likelihood is reduced in relation to task. If the task is outdoors the likelihood reduces
dramatically.
•
The COVID testing is
RELEASED
treated as an additional control. This allows us to move the likelihood of
an event even further.
This is a must. This control is based on the assumption that the testing integrity will be of an
approved standard as per MOH guidelines.
It is useful to be prudent.
The Risk Control Effectiveness:
•
It remains partial, as a result of Medsafe approval status which is provisional consent. Under
Section 20 to 22 (Medicine Act 1981) provisional consent is given to allow patients to access
vaccines despite the data to supports the longer-term safety and efficacy of vaccines is not
yet available.
•
Secondly, MOH guidelines state that vaccines protect people from the effects of COVID-19
but while research is still ongoing to determine whether a vaccinated person could still
transmit the virus to someone else, so to be safe, we must assume there is still a risk of
transmission.

4.2 Stats NZ Risk - Considerations for Internal Organisational movements
Groups traveling in vehicles.
ACT
The same WorkSafe NZ risk assessment needs to be applied to this activity. It still must go back to
role – and the activities that make up that role.
If this is related to Census worker or a Field worker who will then go onto doing some other activities
that increase the risk factors, then it would be considered higher risk.
Frequenting Stats Facilities or facilities utilised by Stats for Stats purposes
INFORMATION
I would agree with the assessment made in
ELT Memo (draft) Section 2. However, I would change
the Alert Levels, as this will change soon to the traffic light system. Instead, government mandated
guidance for workplaces for managing COVID-19 could give the risk assessment more longevity.

Advice from the PSC is where agencies believe there may be a health and safety reason for some
public-facing work to be carried out only by vaccinated workers they must undertake a health and
safety risk assessment of the work. The purpose of the assessment is to determine whether the work
can be done safely by unvaccinated employees. Factors to assess include:
•
nature of the work performed
•
risk of exposure (to and from workers), using the latest advice from the Ministry of Health
•
potential consequences of exposure on others, e.g. community spread
•
effectiveness of options other than vaccination that may be sufficient to mitigate the risk of
exposure (to and from workers).
This assessment should be done with the participation of staff and relevant unions.
5
Working Wise Ltd |Level 4, 24 Johnston Street, Wellington 6011 | [email address] | www.workingwise.nz
If the assessment concludes that there are measures other than vaccination that can ensure the work
can be performed safely, agencies should continue to promote vaccination through the educate,
expect and support approach.
The Stats
NZ ELT Memo (draft V1 and V2) states the intent to continue the assessment process with
ACT
participations from staff and relevant unions. Perhaps this could be emphasised further.
The
Copy of Covid combined census field risk assessment (EXCEL doc) indicates the development of a
COVID-19 vaccination policy through consultation with staff, unions and PSC.
7. ELT Memo – vaccine mandate conclusion
Currently the
ELT Memo (draft V1 and V2) does not make a conclusion that
staff in the roles that
INFORMATION
undertake the tasks that were risk assessed, should be fully vaccinated. This should be clearly stated,
perhaps at the beginning of the memo, or at the end in a
recommendations section.
