In 2020, 28,491 New Zealanders aged 90 and over were recorded as suffering fatal or serious injuries requiring ACC support. By 2024, that figure had dropped to 12,225. That's the lowest level since 2005, when records began tracking this age group separately. (Source: Stats NZ / ACC, fatal-serious-injuries)

What happened between 2020 and now? The timeline tells a story most people aren't paying attention to.

The peak came in 2020 and 2021. Those years saw around 29,000 serious injuries annually among our oldest citizens. Then something shifted. By 2022, the number had plummeted to 12,597. It held steady through 2023 at 12,672, and has now dipped further to 12,225 in 2024.

That's a 57% drop in four years. For context, the number of New Zealanders aged 90-plus has been growing steadily throughout this period. Our population isn't getting younger. So fewer injuries among a larger group of very old people is doubly significant.

The 2020-2021 peak likely reflects the chaos of early COVID years: hospital backlogs, delayed care, more time at home without support networks functioning normally. Falls, medication errors, delayed interventions. All the quiet ways older people get hurt when systems strain.

The drop from 2022 onward suggests those systems recovered. Better home support. Faster hospital response times. Maybe more families keeping closer watch. The data doesn't tell us which interventions worked, but it's clear something did.

Here's what 12,225 serious injuries means in practice: every one of those cases represents a 90-year-old or older Kiwi who fell hard enough to break a hip, suffered a medication complication serious enough to hospitalise them, or experienced trauma severe enough to require ACC coverage for fatal or serious injury. At that age, these aren't minor events. Recovery is measured in months, if it happens at all.

The fact we've cut that number nearly in half since 2020 is one of the quieter public health wins of recent years. No press releases. No ministerial statements. Just a steady decline in elderly New Zealanders being seriously hurt.

The 2024 figure is now back below 2006 levels, despite having far more people in that age bracket. That's not luck. That's safer homes, better care, faster response times. It's the unglamorous work of preventing falls, managing medications, and checking in on people who live alone.

Twelve thousand injuries is still twelve thousand too many. But down from 28,000? That's 16,000 fewer families getting the call. That's worth noticing.
