Compared with other OECD countries NZ is a stand-out success story by ending community transmission of COVID-19. While there have been some well-publicised recent deficiencies (eg, quarantine organisation), there has still been no evidence of community transmission for many weeks. Nevertheless, further improvements in NZ’s response are possible and in this blog we detail how pandemic terminology could be upgraded. Consistent, accurate terminology could assist effective communication between political leaders, officials, scientists, international collaborators and the NZ public on key COVID-19 risk management issues.

In this new study, we estimated the risk of COVID-19 outbreaks associated with air travel from Australia (with a low prevalence of COVID-19 infection) to NZ. We found that the combined use of exit and entry screening, two PCR tests (on days 3 and 12 in NZ), mask use and contact tracing, reduced the risk from one outbreak every 1.7 years (no interventions) to every 29.8 years (95% uncertainty interval: 0.8 to 110). This risk is similar to that achieved by the current system of 14 days quarantine, at one outbreak every 34.1 years (0.86 to 126). In conclusion, multi-layered interventions can markedly reduce the risk of importing the pandemic virus into a COVID-19-free nation like NZ. Whatever approach is chosen, careful management and evaluation will be needed.

Here we present five key reasons for why the NZ Government should establish an official inquiry into the COVID-19 pandemic response. Such an inquiry could identify lessons for the near future (eg, for pandemic control if border control failures occur) but also identify lessons for the organisation and resourcing of public health more broadly. Fortunately, NZ has a fairly solid track record of official inquiries that have resulted in improved systems that advance public safety and public health.
