Description:
Conclusions and Recommendations – draft not completed
Date:
30/03/2022
It is important to keep up to date with the pandemic and to adapt and as rules change.
The initial COVID-19 health and safety risk assessment for DOC workers (staff and volunteers) and workers was undertaken in a Delta environment at a time when many of the population were unvaccinated. Our initial focus and the then MoH
advice was on transmission of Delta which is highly transmissible and carries a risk of harm (severe disease such as hospitalisation, severe illness, and death). The initial health and safety risk assessment was based on multiple layered control
measures which included following MoH guidelines, sanitising or washing hands regularly, where practical wearing a mask and physically distancing around others and staying home if unwell. Relying on advice from MoH, the risk assessment
determined that vaccination against Delta also presented a higher level of protection as a control measure and significantly moved the profile of risk down in terms of likelihood of transmission and severity of consequence. Consequently, DOC’s
COVID-19 Vaccination Policy which came into effect on 16 December 2021 required all DOC workers (unless exempt) to be fully vaccinated and have proof of their vaccination status by way of the My Vaccine Pass. The control measures we
implemented have been effective and fit for purpose.
This review notes (as set out in the first and second reviews we have conducted) that since the risk assessment was conducted, Delta has been overtaken by the Omicron BA.2 sublineage in New Zealand and it is increasingly widespread in
New Zealand with the Omicron peak in Auckland recently with smaller waves expected. This means the COVID-19 risk profile has moved. Experts are advising that the emergence of Omicron, an even more highly transmissible COVID-19
variant means that a threat exists for both vaccinated and unvaccinated people; the MoH advises that people who are fully vaccinated have less protection against transmission of Omicron than for Delta, but that vaccination still offers some
protection. The MoH also advises that protection against infection with either Delta or Omicron decreases over time. A booster dose at 4 months after the end of the first dose will improve protection against Omicron particularly for protection
against severe disease such as hospitalisation although does not result in as many people being hospitalised. Omicron can still cause severe illness and even death especially in people who are at risk of severe outcomes. MoH advice is that
getting boosted continues to be one of the most important ways people can protect themselves from Omicron and severe illness. There is a much lower risk of being hospitalised if up to date with vaccinations which for Omicron includes a third
of booster dose if eligible. As community transmission of Omicron increases, it is less likely there will be a greater risk of COVID-19 in DOC visitor accommodation than there is in the community.
Some specialist medical and scientific experts including the MoH advise that New Zealanders need to plan for and expect further variants as the COVID-19 virus will continue to adapt to survive, and they warn us that Omicron is not to be
underestimated as the impact on the body or the impact of long COVID-19 is not fully understood.
Border controls have recently changed, and the Government no longer requires incoming vaccinated New Zealanders and other vaccinated travellers to self-isolate on entry to New Zealand. Australian tourists who are vaccinated will be able to
travel to New Zealand from 12 April 2022. These changes introduce an increased level of risk to New Zealanders as these people may be asymptomatic, but they bring with them the risk of seasonal illnesses including the super cold some
Australians are experiencing.
Changes have also been made to the way close and household contacts are managed by MoH under Omicron Phase 3 Red which increases the likelihood of an infectious people being in the community, and hence increasing transmission in
the community but significantly this also increases population or herd immunity.
The Government has recently announced that CVCs7 will no longer be a requirement at any traffic light setting after 4 April 2022 at 11:59pm. This is irrespective of what traffic light setting is in place past this date. The technology for My Vaccine
Passes will remain available (and is being updated to include boosters) but there will be no mandate requiring its use. The rationale for this change is that we have moved past the point where CVCs are most effective. This approach is being
taken by the Government in light of the high vaccination rate (currently 95.1% of eligible New Zealanders are vaccinated which means many people may not have symptoms at all but still be able to pass on the virus to others), there are high
levels of acquired immunity from the Omicron outbreak and given the features of Omicron. Omicron BA.2 breaks through the vaccination barrier. However, MoH advise that vaccination (including boosters) continues to be strongly recommended
as one of the key public health measures and it provides significant benefits. The Government has indicated that My Vaccine Passes could become mandatory again in the future if there are different variants or circumstances change.
DOC is still able to close its workplaces where there is a high risk that is not easily mitigated and is required to work with iwi, communities, and campsite managers to assess risk for specific sites and support them regarding restrictions or
closures needed for public safety.
We cannot predict the future with any certainty as to how the pandemic will unfold. We act on best, most up to date official information available, remain vigilant, keep the health and safety risk assessment under review and ourselves briefed on
most up to date health advice from the MoH.
Considering the matters referred to above and bearing in mind we are entering the winter season which usually means fewer people in our accommodation (some of which will be seasonally closed), this review supports retention of all existing
control measures in DOC accommodation that is open to the public and/or our workers except for the requirement to provide proof of vaccination status for entry. The rapidly changing nature of COVID-19 means we should retain the ability to
require My Vaccine Passes in the future.
Recommendations:
(1) Unvaccinated workers and contractors to DOC workplaces no longer be required to provide proof of vaccination status with a My Vaccine Pass.
(2) Retention of the current Vaccination Policy and the ability to use CVCs as part of health and safety. To this end, it is recommended that the Vaccination Policy be suspended as of 4 April 2022 at 11:59pm to coincide with the
Government’s rol back of My Vaccine Passes.
(3) Use of alternative controls, additional controls transitioning unvaccinated staff (and vaccinated who have been working off-site) into the workforce
(4) Localised risk assessments re control measures relevant to each workplace
(5) Continue to monitor official health advice and observe current health risk levels in the community.
(6) Undertake the formal review of the risk assessment referred to in the Vaccination Policy as scheduled on 31 May 2022 (unless there is a need to undertake this sooner).
