Abstract
Objectives: Aotearoa New Zealand employed one of the most stringent public health pandemic responses internationally. We investigated whether ethnic health equity was achieved in the response and outcomes, from COVID-19 elimination in June 2020 through to Omicron-response easing, including international border reopening, in 2022.
Study design: Descriptive epidemiology study.
Methods: All COVID-19 cases, patients tested for SARS-CoV-2 and people vaccinated against COVID-19 between 9 June 2020 and 13 April 2022 were examined over three response periods: by demographic features and COVID-19 outcomes, transmission and vaccination patterns, time-to-vaccination and testing rates.
Results: There were 15,693 cases per 100,000, 138·7 hospitalisations per 100,000, and 9·8 deaths per 100,000 people. Pacific peoples and Indigenous Māori had, respectively, 9·3 to 35-fold and 1·5 to 8·3-fold higher risk of COVID-19, 5·1-fold and 2·6-fold higher age-standardised risk of hospitalisation and 9-fold and 4-fold higher age-standardised risk of death, than European or Other. Māori and Pacific peoples had lower vaccination coverage at critical points in the response, and slower access to vaccination (Adjusted Time Ratios for two doses 1·32 (95% CI 1·31–1·32) and 1·14 (1·14–1·14), respectively), than European or Other. Testing rates remained high, especially among Māori and Pacific peoples.
Conclusions: Despite achieving a low overall burden of disease by international comparisons, the multi-faceted New Zealand response did not prevent stark ethnic inequities in access to vaccination and COVID-19 outcomes. Policies which address disparities in upstream determinants, early vaccine programme planning and implementation with high-risk communities, and prioritisation that addresses systematic ethnic disadvantage and promotes health equity in response decisions is recommended.
