NZ has now achieved the lowest death rate from the COVID-19 pandemic out of 37 OECD countries and appears to be the only one to succeed with elimination at a national level. But despite the success of the “team of 5 million” – there are still a number of gaps in our defences. In particular, there is a need to upgrade: (i) border controls; (ii) the Alert Level system; (iii) the use of digital technologies to support contact tracing; (iv) testing & surveillance for early outbreak detection; (v) the kinds of policies, institutions and laws needed to sustain our world-class response.

Health and emergency laws have played a critical role in this country’s successful elimination of community transmission of the COVID-19 pandemic. This blog details key aspects of the legislation and comments on issues around testing, payments by incoming travellers for quarantine costs, and mask use. Continue reading

This blog details a recent modelling study we conducted. In it we estimated that it would take between 27 and 33 days of no new detected cases of COVID-19 for there to be a 95% probability of epidemic extinction in NZ (at around current testing levels). For a 99% probability of epidemic extinction, the equivalent time-period was 37 to 44 days. So now the country urgently needs the Ministry of Health to provide an official definition of elimination and to upgrade the data on its website so that the public, the media and researchers can monitor progress towards achieving the goal.

The concepts of an Alert Level system, household “bubbles”, and social event size limits are all valuable pandemic control measures. Nevertheless, better “source control” of COVID-19 at various Alert Levels by requiring masks in public indoor spaces could reduce the risk of outbreaks (should there be border control failures) and reduce the likelihood that we would need to move back to tighter restrictions and lockdowns with the associated adverse economic, social and mental health effects.

In this blog we identify six likely benefits from requiring fabric mask use in public transportation and border control settings in the “peri-elimination” context that New Zealand is currently in. Given these likely benefits and the relatively low costs (especially if the Government provides free masks as per Hong Kong), such a policy should be given very serious consideration by health authorities in the transition to level 2.
