We talk endlessly about workplace safety getting worse. About stretched health and safety budgets, about corners being cut, about the risks workers face. But here's what the data actually shows: New Zealanders aged 55 to 59 are now half as likely to suffer a fatal or serious workplace injury as they were in 2020.

In 2020, ACC recorded 10,350 fatal and serious injuries for this age group. By 2024, that number had fallen to 4,734. You have to go back to 2002 to find a comparable figure. This is the safest this demographic has been at work in 22 years (Source: Stats NZ / ACC, fatal-serious-injuries).

The drop isn't gradual. It's dramatic. From 2020 to 2022, the numbers nearly halved. They've stayed low since. Whatever changed in those two years, it worked.

This matters because people in their late fifties are among the most experienced workers we have. They've spent decades in their industries. They know the risks. And yet, historically, they've been overrepresented in serious injury statistics. Older bodies don't bounce back as easily. A fall that bruises a 25-year-old can hospitalise someone pushing 60.

So what happened? The timing points to COVID. Lockdowns forced dangerous industries to pause. Construction sites went quiet. Physical labour slowed. When work resumed, maybe some of the riskiest practices didn't come back. Maybe older workers negotiated safer roles. Maybe companies, facing scrutiny and staff shortages, finally invested in injury prevention.

Or maybe it's simpler: fewer older workers are doing the most dangerous jobs. Early retirements surged during the pandemic. Some never returned. If the workers most at risk of serious injury aren't on site anymore, the injury numbers fall.

Either way, the result is the same. This age group is safer at work than it has been in a generation. That's not a small thing. Every one of those 5,616 fewer injuries in 2024 compared to 2020 represents someone who went home intact. Someone who didn't spend months recovering. Someone whose family didn't get a phone call from a hospital.

Good news in safety data is rare enough that it deserves recognition. But it also demands a question: if we managed to halve serious injuries for 55-59 year-olds in four years, why can't we do the same for every other age group? What worked here, and where else can we apply it?

The data doesn't answer that. But it does prove something we don't say often enough: workplace safety can improve, dramatically, in a short time. We just have to care enough to make it happen.
