National review of avoidable deaths

In 2023 around 38,000 people died in Aotearoa, of which up to a quarter were potentially avoidable. We establish and report on how ethnicity, deprivation, the urban/rural divide, age, employment status, disability and access to medical care impact mortality. Our current programme includes four workstreams: child and youth, perinatal and maternal, perioperative, family violence.
