The political debate about crime is loud right now. Rising youth offending. Gang violence. Retail crime. Politicians on all sides have their talking points ready.

But here's what nobody's mentioning: in the Bay of Plenty, courts convicted 233,068 adults in 2024. That's the lowest number since 1987, when the region's population was significantly smaller.

This isn't a one-year blip. It's part of a longer slide. In 2020, Bay of Plenty courts convicted 246,728 adults. By 2024, that figure had dropped by 13,660 convictions, a fall of 5.5%. (Source: Ministry of Justice, adults-convicted-by-sentence)

You can read this data two ways. Either adults in the Bay of Plenty are committing fewer crimes worth prosecuting, or the justice system is processing fewer cases to conviction. Both interpretations matter.

The regional context is important here. The Bay of Plenty has one of New Zealand's fastest-growing populations. Tauranga alone added thousands of residents over this period. When population rises and convictions fall, the per-capita drop becomes even steeper.

This doesn't mean crime has vanished. It means the specific metric we use to measure justice system outcomes. adults found guilty in court. is at a 37-year low. That's a fact that should shape how we talk about what's happening in our communities.

The 2022 dip to 233,324 convictions was briefly interrupted in 2023, when numbers climbed back to 241,384. But 2024 resumed the downward trend, landing just below the 2022 figure.

Here's what this data can't tell you: whether crimes are going unreported, whether police are laying fewer charges, or whether court backlogs are creating delays that push convictions into future years. Those are valid questions. But they're separate from what the conviction data itself shows.

What it does show is this: the Bay of Plenty justice system convicted fewer adults in 2024 than in any year since 1987. That's not a talking point. It's not a political spin. It's what the Ministry of Justice recorded.

When the crime debate heats up again, someone will pull out a statistic to prove their point. Make sure you know what the full dataset actually says.
