A Royal Commission of Inquiry into New Zealand’s COVID response started work this month, with a aim to organize the nation for future pandemics.
It will give attention to classes not solely from New Zealand’s pandemic expertise but additionally from different nations and jurisdictions.
Early within the pandemic, it turned clear some nations had greater numbers of COVID deaths than others. New Zealand and Iceland had the bottom mortality amongst high-income nations: positioned first and second within the OECD for lowest extra mortality as of June 2022, respectively.
A earlier article outlined classes from each Iceland and New Zealand in September 2020. In a not too long ago revealed examine, we prolonged this comparability by to June 2022.
At the start of the pandemic, each nations quickly carried out comparable management measures, together with testing, contact tracing, isolation and quarantine, gathering limits and bodily distancing. Both nations have been comparatively sluggish to require mass masking.
Rapid border administration was possible simpler in these nations as a result of each are island nations with just one (Iceland) or just a few (New Zealand) worldwide airports. However, each nations needed to work shortly to extend testing and get in touch with tracing capability and buy further private protecting tools for healthcare employees.
But other than these measures, the 2 nations pursued totally different methods.

Elimination or mitigation
Iceland didn’t implement an elimination technique and as an alternative centered on mitigation, although neighborhood transmission was eradicated early on. Iceland’s response didn’t contain the usage of lockdowns or official border closures.
Meanwhile, New Zealand initially deliberate to comply with a mitigation technique, however then shifted shortly to an elimination technique early within the pandemic. It employed the usage of a strict lockdown and largely closed its worldwide border (although low ranges of important journey continued with two weeks of quarantine for returning residents on the border).

Elimination seeks to scale back transmission to zero inside an outlined jurisdiction. By comparability, management methods like suppression purpose to maintain case numbers low to minimise sickness and demise. Mitigation implies lighter controls, extra calibrated in direction of stopping well being methods turning into overwhelmed.
In New Zealand, the elimination technique labored within the early levels of the pandemic and allowed for a return to near-normal life for most individuals within the nation. That was till late 2021, when an outbreak of the Delta variant led the federal government to shift to a suppression technique.
Then, following a wave of the Omicron variant in early 2022, New Zealand started to reopen its border in levels, marking a shift to mitigation.

The financial prices of the pandemic
Iceland and New Zealand each launched financial interventions shortly after the primary COVID instances have been detected. Government provision of economic help as a proportion of GDP in 2020 and 2021 was twice as excessive in New Zealand as in Iceland.
Despite financial assist measures, each nations noticed a contraction in GDP in 2020, though a lot better in Iceland (-8·27% vs -1·22%). Iceland additionally skilled a better peak unemployment charge (7·2% vs 5·3%), however with a fast rebound in 2021. This distinction might partly replicate Iceland’s stronger reliance on its tourism sector, nevertheless it’s additionally doable the measures taken in New Zealand have been simpler for supporting its financial system.
There have been many similarities between Iceland’s and New Zealand’s responses. Both nations had current common healthcare protection and pandemic plans focused in direction of influenza. However, neither nation had a devoted nationwide establishment to answer infectious illnesses.
There was clear communication involving common briefings by senior officers in each Iceland and New Zealand. This included day by day press briefings that have been nationally broadcast and early communications concerning the pandemic framed as a shared risk. In Iceland the phrase “we’re all civil safety” was generally used, whereas in New Zealand, there was frequent reference to the “workforce of 5 million”.
Scientists additionally performed a very outstanding function within the response. There was a excessive stage of public belief within the response in each nations, particularly early within the pandemic.
Differences in vaccination and testing
Iceland carried out a lot better than New Zealand with vaccination, starting its marketing campaign a number of months earlier. The sluggish progress with vaccination in New Zealand was some extent of criticism on the time (together with delays in reaching Māori and Pasifika) and must be an space of focus for the Royal Commission of Inquiry.

Nevertheless, New Zealand did catch as much as Iceland. By June 2022, each nations had comparable vaccination protection charges. Differences within the timing of vaccination in all probability had little internet impact.
Iceland’s success at retaining COVID instances and deaths comparatively low with out the usage of stringent restrictions led to the query of whether or not New Zealand may have achieved comparable outcomes with out a border closure and lockdowns.
It appears to us unlikely New Zealand may have achieved comparable outcomes with out considerably rising testing capability. Iceland carried out nearly 4 occasions extra assessments (per 1000 inhabitants) than New Zealand through the examine interval. This improve in capability was made doable partly by collaboration with deCODE Genetics.
While efforts to extend testing capability in New Zealand progressed quickly within the first yr of the pandemic, a backlog developed through the preliminary stage of the Omicron wave in early 2022 as a result of many laboratories have been overwhelmed by the variety of assessments.

The keys to stopping future pandemics
Considering the influence of different pandemic responses is difficult, however nation comparisons may give some clues. Also, illness modelling means that had New Zealand delayed implementing its lockdown, the primary pandemic wave would have been bigger and brought longer to manage. Elimination might need grow to be unattainable.
Overall, most of the pandemic management measures deployed by Iceland and New Zealand appeared profitable. Features of the responses in each nations may doubtlessly be adopted by different jurisdictions to deal with future pandemic threats. Indeed, a few of us have argued elimination must be the default technique for future pandemics above a sure severity.
