That's a really nice presentation that neatly explains why no single measure is going to defeat the beast, thanks Sheri :ok:

Welcome to the wormhole that is employment, health & safety and Covid Vaccinations,

Workers do not have to tell their employer if they have been vaccinated or why they are unable or choose not to be vaccinated. If workers have consented, the Ministry of Health can inform employers whether Group 1 workers have been vaccinated. Employers can ask workers if they have been vaccinated. If workers do not tell employers what their vaccination status is, employers may assume workers are unvaccinated, but should first inform workers of this assumption. — Employment New Zealand

If you think a role in your business or service needs to be performed by a worker vaccinated against COVID-19, you need to assess the role’s exposure risk to the virus. A strong indicator is if the role currently requires mandatory regular COVID-19 testing under the COVID-19 Public Health Response (Required Testing) Order 2020. — Assessing whether a specific role needs to be performed by a vaccinated worker

When carrying out a risk assessment, you’ll need to consider:

the likelihood of workers being exposed to COVID-19 while performing the role, and
the potential consequences of that, eg community transmission — MBIE
