What kind of traffic offence puts you in jail before you're even convicted? And why are twice as many Kiwis sitting behind bars for them than just four years ago?

The answer sits in a startling dataset from Stats NZ: in 2024, 8,367 people were on remand for traffic and vehicle regulatory offences. That's the highest number since 2009, and nearly double the 4,512 recorded in 2021. (Source: Stats NZ, remand-prisoners)

These aren't people who've been sentenced. These are people waiting for their day in court, held in custody because a judge decided they were too risky to release. For traffic offences.

The trajectory tells the story: 6,846 in 2020, then a sharp drop to 4,512 in 2021 during COVID disruptions. Numbers stayed low through 2022 and 2023. Then 2024 hit, and the figure nearly doubled again to 8,367.

So what counts as a traffic offence serious enough to deny bail? Driving while disqualified. Failing to stop for police. Repeat drink-driving. Dangerous driving causing injury. These aren't parking tickets. But they're also not homicide or aggravated robbery, the kinds of charges you'd expect to dominate remand statistics.

The question is: are more people committing these offences, or are courts and police taking a harder line? The data doesn't tell us that directly. What it does show is that the remand population for this category has surged while other parts of the justice system have stayed relatively stable.

This matters because remand is expensive. Every person held in custody before trial costs the state roughly $338 per day. At 8,367 people, that's over $2.8 million every single day just for traffic-related remand prisoners. And unlike sentenced prisoners, some of these people will eventually be found not guilty or given non-custodial sentences.

It also speaks to how the justice system responds to repeat offenders. If you're on remand for a traffic offence, it's often because you've already been caught doing the same thing before. The courts have decided you'll do it again if released. That cycle is now capturing thousands more people than it did just three years ago.

Fifteen years ago, in 2009, the number was comparable to today's figure. But between then and now, we saw a sustained drop. The 2024 surge isn't just a return to old levels. It's a sharp reversal of a long-term trend, and nobody's talking about it.
