A Māori scaffolder in Auckland, taking a fall that would have sent him to hospital in 2021. By 2022, that same fall might not have been recorded at all.

Something dramatic happened to workplace injury statistics for Māori between 2021 and 2022. The numbers tell a story of either remarkable progress or a fundamental shift in how injuries were counted.

In 2021, 74,934 serious injuries involving Māori workers were recorded by ACC. Twelve months later, that figure was 34,086. That's a drop of 40,848 cases in a single year.

The decline wasn't temporary. The numbers stayed low: 33,675 in 2023, 32,916 in 2024. Over three years, the count has barely moved from that new baseline.

To understand how unusual this is, look at the trajectory. From 2020 to 2021, the figure climbed from 72,756 to 74,934. Standard year-on-year variation. Then came 2022, and the floor dropped out.

Three explanations exist. First: workplaces became radically safer for Māori workers almost overnight. Second: fewer Māori workers were in dangerous jobs after 2021. Third: something changed in how ACC categorised or recorded these injuries. (Source: Stats NZ / ACC, fatal-serious-injuries)

The timing matters. COVID-19 lockdowns disrupted work patterns in 2020 and 2021. Construction sites closed. Hospitality shut down. Meat processing plants ran skeleton crews. When work resumed in 2022, perhaps the mix of jobs had shifted. Perhaps safety protocols tightened. Perhaps younger, less experienced workers had left those industries entirely.

But a 54% drop in serious injuries to any demographic group, in one year, is not a normal safety improvement. That's not the result of better hi-vis vests or extra training courses. That's either a structural change in the workforce or a definitional change in what gets counted.

The 32,916 figure for 2024 means that every day, roughly 90 Māori workers are getting seriously injured. That's still 90 people dealing with broken bones, burns, crushed limbs, or worse. But it's 115 fewer than in 2021.

If this drop represents genuine progress, it's a story worth celebrating and understanding. If it represents a change in counting, then 40,000 injuries didn't disappear. They just stopped being visible in the data.

Either way, the question stands: where did those 40,000 cases go?
