A Māori worker in the construction sector today is half as likely to be seriously injured as they were in 2020. That's not a small improvement. That's a seismic shift in workplace safety, concentrated in a single demographic group, over just four years.

The numbers: in 2020, 72,756 Māori were seriously injured at work or in accidents covered by ACC. By 2024, that figure had fallen to 32,916. That's a 55% drop in four years (Source: Stats NZ / ACC, fatal-serious-injuries).

This comes the same week a person was injured in a dog attack in Timaru, a reminder that ACC's definition of 'serious injury' captures everything from workplace accidents to off-the-job incidents. But even accounting for that breadth, the pattern is stark.

Compare it to the overall trajectory. New Zealand's total serious injury count has also fallen, dropping from around 204,000 in 2020 to roughly 165,000 in 2024. But the Māori decline is steeper, faster, and more dramatic. Whatever changed in 2022, it hit this group hardest.

The question is: what happened? The data doesn't tell us. But it does tell us when. The inflection point is 2022. That's when Māori serious injuries dropped from 74,934 to 34,086. Not a gradual decline. A cliff.

Was it safer workplaces? Better training? A shift in the industries employing Māori workers? The data doesn't say. But the timing matters. 2022 was the year New Zealand emerged from the worst of the pandemic restrictions. It was also the year the construction sector began to cool after a years-long boom. Both of those could explain part of the drop.

But here's the uncomfortable bit: if 32,916 Māori were seriously injured in 2024, that's still 90 people every single day. The number has halved. It's still enormous.

And it's still higher, proportionally, than it should be. Māori make up roughly 17% of New Zealand's population. If serious injuries were evenly distributed, they'd account for about 28,000 of the national total. Instead, they account for nearly 20% of all serious injuries, even after the drop.

The halving of Māori workplace injuries is one of the most dramatic safety improvements in recent New Zealand history. But it's also a story about how far we still have to go. If the number can drop by 40,000 in four years, what's stopping it from dropping by another 10,000 in the next four?

The data doesn't answer that. But it does ask the question.
