In 2024, New Zealand's justice system imposed 5,610 community sentences on people it categorised as "inadequate data available." That's not a crime category. That's not a sentencing type. That's what happens when the system doesn't record who it's sentencing.

This is the highest number in 25 years. You have to go back to 1999 to find anything comparable. And it's not a gradual drift: it's a collapse in data collection that happened recently and fast.

In 2019, just 90 community sentences fell into this category. By 2022, it had jumped to 1,977. Now it's nearly three times that again. Something broke in the last two years, and nobody's talking about it.

Community sentences are the justice system's main alternative to prison: community work, supervision, home detention, intensive supervision. These aren't trivial. They're court-ordered restrictions on someone's freedom, sometimes lasting years. And in 5,610 cases last year, we don't know the age, ethnicity, or gender of the person being sentenced.

Here's the contrast that should worry you: at the same time politicians are arguing over whether crime statistics prove their point, the actual data collection system is falling apart. We're having heated debates about who commits crime and what works to reduce it, based on datasets that are increasingly incomplete.

This isn't a story about missing paperwork. It's a story about accountability. When courts don't record basic facts about who they're sentencing, we can't answer fundamental questions. Are community sentences being applied fairly across demographics? Are certain groups more likely to breach their conditions? Which interventions actually work for which people?

The trajectory tells you this isn't an accident. In 2018, inadequate data affected 309 sentences. Then it dropped to 90 in 2019. Something improved. Then something else broke. By 2024, we're at 18 times the 2019 level.

This matters because community sentences are where the justice system tries to rehabilitate people instead of locking them up. If we don't know who's getting these sentences, we can't know if they're working. We can't compare outcomes. We can't learn what reduces reoffending.

And we definitely can't have honest policy debates about criminal justice when a growing chunk of the data is just.. missing.
