7 - Lockdowns Ngā noho rāhui
Introduction | Kupu whakataki
The first reported case of COVID-19 in Aotearoa New Zealand was detected on 28 February 2020, more than two months after the virus was identified in China, and a week or so after small clusters were identified in Europe and the United States. This delay – attributable partly to geographic isolation, and partly to good luck – meant Aotearoa New Zealand had an important opportunity to assess what was happening in other countries before taking action.12
...Cabinet made an informed decision to adopt ’aggressive and effective containment measures’, such as closing the border.
In particular, once COVID-19 started to spread significantly in other countries, decision-makers were able to compare the experience of Italy and parts of the United States (where rapid community transmission had already overwhelmed hospitals and caused many deaths) with that of China, Taiwan and Singapore (where authorities had adopted strong restrictions which somewhat contained the virus).13 On that basis, Cabinet made an informed decision to adopt ’aggressive and effective containment measures’, such as closing the border.14
As part of this approach, Aotearoa New Zealand, like much of the world, went into ’lockdown’ in late March 2020.v However, the rationale for New Zealand’s lockdown – to break chains of transmission – soon diverged from the rationale in most other parts of the world, where lockdowns were used to keep transmission down to an ’acceptable’ level.15 This usually meant a level that did not overwhelm health services.
As the need for such a tool had never been anticipated or prepared for, Aotearoa New Zealand had no apparatus in place for an all-of-society lockdown ahead of the COVID-19 pandemic. The whole public sector – including those working in both frontline and public health roles – was operating without a playbook, as indeed was everyone in Aotearoa New Zealand.
On 23 March 2020, the number of confirmed cases in Aotearoa New Zealand passed 100,16 and the Prime Minister announced that the country would move immediately to Alert Level 3, followed by Alert Level 4 in 48 hours.17 From this point, Aotearoa New Zealand was in ’lockdown’.
“If community transmission takes off in New Zealand the number of cases will double every five days. If that happens unchecked, our health system will be inundated, and thousands of New Zealanders will die...Moving to Level 3, then 4, will place the most significant restrictions on our people in modern history but they are a necessary sacrifice to save lives. ”18
Prime Minister Ardern, 23 March 2020
v ’Lockdown’ was not an official legal term but was used by Prime Minister Jacinda Ardern in a press release announcing the first lockdown (see endnote 15 for details). It emerged in global use early in the COVID-19 pandemic to describe combinations of public health measures that heavily curtailed people’s movement in the interests of stopping the virus. Levels 3 and 4 of New Zealand’s Alert Level System can be understood as ’soft’ and ’hard’ lockdowns, respectively, because they required people to stay at home, closed schools and businesses, and involved heavy restrictions on public gatherings. We use ’lockdown’ to describe these aspects of the response, since they were a defining part of the pandemic experience, and most people remember and refer to them this way.
