A 57-year-old tradesman in Christchurch. A warehouse worker in Hamilton three years from retirement. A farmer in Taranaki who's been working the same land for decades. Four years ago, over 10,000 workers in their late fifties suffered serious enough injuries to show up in ACC's records. This year, that number is 4,734.

That's the lowest rate of serious workplace injuries for 55-59 year olds since 2002. It's a 54% drop from 2020, when the figure hit 10,350. And nobody's talking about it.

The timing matters. Tower Insurance just announced weather-related claims will nearly halve their profits, a reminder that New Zealand is getting more expensive to insure. But while extreme weather batters our infrastructure, something's clearly working in our workplaces, at least for this age group.

These aren't minor scrapes. ACC's serious injury data captures hospitalisation-level harm: broken bones, severe lacerations, back injuries that end careers early. For workers in their late fifties, these injuries don't just hurt. They can mean forced early retirement, reduced KiwiSaver balances, years of reduced income before the pension kicks in at 65.

The decline isn't gradual. It's a cliff. From 2020 to 2022, the number dropped from 10,350 to 4,929. It's held roughly steady since, hovering around 4,900. That suggests this isn't statistical noise or a recording change. Something shifted in how older workers are being protected, or how they're working.

The pattern raises questions. Did COVID-19 force safer work practices that stuck? Did older workers move into less physical roles during the pandemic and stay there? Or are businesses finally taking the physical limits of aging workers seriously, after years of pressure from unions and WorkSafe?

The data doesn't answer those questions. But it does tell us this: if you're 57 and still working, you're statistically half as likely to end up in hospital from a workplace injury as you were four years ago. (Source: Stats NZ / ACC, fatal-serious-injuries)

That's 5,616 fewer serious injuries in 2024 compared to 2020. Thousands of late-career workers who kept their bodies intact, their incomes steady, their retirements on track. In a year where insurance costs are climbing and extreme weather is reshaping New Zealand's risk profile, here's one number moving in the right direction.

It won't make headlines like flooding or political accusations. But for the 57-year-old who finished their shift today without a trip to A&E, it matters more than anything in the news.
