📉 NZ 2025: Public Convictions vs Police Investigations — A Per‑Capita Breakdown the Government Never Publishes

BY NIGEL GRAY INDEPENDENT INVESTIGATOR 4 SEPTEMBER 2026

New Zealanders are told that crime is a “public problem.”
But the numbers from 2025 tell a very different story — one the official agencies never place side‑by‑side.

This is the first forensic comparison of public convictions versus police investigations, adjusted per capita using official population and workforce numbers.

And the result is simple:

In 2025, NZ Police were investigated at a higher per‑capita rate than the public were convicted.

Let’s walk through the numbers.

1. Public Convictions (2025)

Stats NZ and Ministry of Justice data show:

32,797 adult convictions

Population: ~5,250,000

Per‑capita conviction rate:

32,7975,250,000≈0.00625⇒≈ 6.2 convictions per 1,000 people

This is the number politicians quote when they talk about “public crime.”

But they never compare it to their own institution.

2. Police Investigations (2025)

This is where the picture flips.

The breath‑test falsification scandal

RNZ reporting confirmed:

100+ police officers investigated

30,000 falsified breath tests

Multi‑district misconduct

Dishonesty, coercion, record manipulation

This scandal alone exceeds the entire annual number of police officers charged or convicted.

Other 2025 investigations (criminal + misconduct)

Media‑verified cases include:

Objectionable publication offences (Deputy Commissioner)

Assault with a weapon

Dangerous driving causing injury

Fraud/dishonesty

Privacy breaches

Sexual misconduct

Excessive force

Falsified reports

Minimum additional officers: 12

Total minimum police investigated (2025):

100+12=112 officers

Police workforce:

~15,600 staff

Per‑capita investigation rate:

11215,600≈0.00718⇒≈ 7.2 investigations per 1,000 staff

NZ Police — Investigated≥11215,600 = 7.2

Police were investigated at a higher per‑capita rate than the public were convicted.

This is not a political statement.
It is arithmetic.

3. Why This Matters

A. Investigations are the real indicator of misconduct volume

Convictions are the endpoint.
Investigations show the scale.

B. Police numbers are “sanitised”

When an officer is investigated, they are often:

stood down

suspended

quietly removed

allowed to resign

This means the police workforce denominator shrinks, artificially lowering per‑officer rates.

The public denominator never shrinks.

C. The public is measured by convictions; police are measured by silence

There is:

no annual police investigation report

no annual police misconduct count

no annual police criminal charge tally

no annual police conviction dataset

The public is measured.
The police are protected.

4. The Contradiction at the Heart of NZ’s Crime Narrative

New Zealand’s political messaging frames crime as a public failing.

But the numbers show:

Public conviction rate: 6.2 per 1,000

Police investigation rate: 7.2 per 1,000

The institution responsible for enforcing the law is investigated more often per capita than the population it polices.

This is not a fringe claim.
It is a structural contradiction.

5. The Question New Zealand Should Be Asking

If the public is judged by convictions,
and the police are judged by nothing,
what does that say about accountability?

And more importantly:

Why is the only institution with guns, immunity, and coercive power the one with the least transparent misconduct reporting?

6. Closing

This comparison is not available in any official publication.
It is not produced by NZ Police, IPCA, Stats NZ, or the Ministry of Justice.

It exists only when someone puts the numbers together.

Now it’s public.
