On the same day a person was injured in a dog attack in Timaru and salami products were recalled over safety concerns, another safety story went entirely unnoticed: New Zealand's oldest workers are now getting hurt at rates we haven't seen in nearly two decades.

In 2024, 12,225 people aged 90 and over suffered serious injuries. That's the lowest figure since 2005. Four years ago, in 2020, that number was 28,491. In other words, serious injuries among New Zealand's oldest citizens have been cut by more than half. (Source: Stats NZ / ACC, fatal-serious-injuries)

This isn't a small cohort. We're talking about twelve thousand people in their nineties and beyond who experienced injuries serious enough to require ACC support. But the trajectory tells a story that contradicts every narrative about an ageing population becoming more vulnerable.

Something changed in 2022. The data shows 12,597 serious injuries that year, down from 29,499 the year before. That's not a gradual decline. That's a cliff edge. The number has barely moved since: 12,672 in 2023, 12,225 in 2024.

The question nobody seems to be asking: why did injuries among the oldest New Zealanders suddenly halve between 2021 and 2022? Was it changes in how ACC categorises injuries? Shifts in where this age group lives or works? Different reporting thresholds?

What we do know is this: if you're 90 or older in New Zealand today, you're statistically safer than you've been at any point in the past 19 years. The data doesn't tell us why. It just tells us that while public attention fixates on individual incidents and product recalls, something fundamental shifted in how our oldest citizens are experiencing serious injury.

The numbers themselves are still significant. Twelve thousand injuries in a single year for one age cohort is not nothing. Each one represents someone's grandmother, great-uncle, or neighbour who ended up needing medical intervention serious enough for ACC to step in.

But the trend is undeniable. Between 2020 and 2024, New Zealand managed to make life dramatically safer for people in their tenth decade. We just haven't noticed yet.
