Summary and Key Findings
What's Not Included in This Data
The Crash Analysis System, where our data is sourced from, records crash circumstances and outcomes, including where crashes occurred, road conditions, vehicles involved, and objects struck. However, this dataset does not include driver behaviour factors such as:
These factors are assessed separately through Police investigation - we do not have access to that data. This guide focuses on what the CAS data can reliably tell us about crash locations, severity patterns, and road characteristics.
- 91,496 crashes over three years resulted in 984 deaths - one death every 27 hours on average
- Crashes are declining: Down 8.4% overall, deaths down 13.9% from 2022/23 to 2024/25
- Northland's death rate is 10× higher than Auckland's (19.4 vs 1.8 per 100,000 people)
- 100kph roads account for 26% of crashes but 56% of deaths - the fatal crash rate is 5× higher than 50kph roads
- Rural roads have 36% of crashes but 71% of deaths - this is nearly 4× the urban fatal rate
- Motorcyclists face an extreme risk: 3.5% fatal crash rate, which is 4.6× higher than that of cars
- What you hit matters: Water/river crashes have a 6.6% fatal rate vs 0.3% for parked vehicles (arguably understandable)
- Traffic signals reduce fatal rates by 4× compared to uncontrolled intersections
- Christmas/New Year is the deadliest period with a 1.90% fatal rate - more than double Easter
What's Not Included in This Data
The Crash Analysis System, where our data is sourced from, records crash circumstances and outcomes, including where crashes occurred, road conditions, vehicles involved, and objects struck. However, this dataset does not include driver behaviour factors such as:
- Alcohol or drug involvement
- Fatigue
- Distraction (e.g. mobile phone use)
- Speeding as a contributing factor (we can only analyse posted speed limits, not whether drivers exceeded them)
These factors are assessed separately through Police investigation - we do not have access to that data. This guide focuses on what the CAS data can reliably tell us about crash locations, severity patterns, and road characteristics.

Know This First: Where We Sourced Our Data
Important caveats:
- Data Source: Waka Kotahi NZ Transport Agency Crash Analysis System (CAS)
- What's Included: All police-reported traffic crashes on New Zealand roads
- Reporting Period: Three complete financial years - 2022/2023, 2023/2024, and 2024/2025 (July 2022 – June 2025)
- Total Records: 91,496 individual crash events
- Data Points Per Crash: 72 variables, including location, severity, vehicles involved, road conditions, weather, and objects struck
- What This Means: This is the official crash record for New Zealand. Unlike car insurance claims data (which shows what's reported to insurers), this captures all incidents attended by police - including those without insurance claims.
- Population Data: Regional populations from Stats NZ 2023 estimates used for per-capita calculations.
Important caveats:
- Minor crashes (especially property-damage-only) are under-reported to police
- Fatal and serious injury crashes are comprehensively captured
- Per-capita rates use regional population, which have changed slightly since 2023
- Financial year data runs from July to June
The Bigger Picture - What the Ministry of Transport's Data Tells Us
Our top must-knows include:
1. Regional inequality in road safety is stark
A driver in Northland is 10 times more likely to die on the road than a driver in Auckland. This isn't about driving skill - it's about road design, speed limits, emergency response times, and the age of the vehicle fleet.
Our View: If you live in a high-risk region, your car insurance premium reflects this reality. The data shows regional pricing isn't arbitrary - dramatically different death rates actuarially justify it.
2. Speed is the clearest predictor of death
The jump from 50kph to 100kph roads isn't just double the speed - it's 5× the fatal crash rate (0.39% vs 2.02%). Physics doesn't negotiate.
Our View: The debate around speed limit reductions is contentious, but this data shows why safety advocates push for lower limits on high-risk roads. Every 10kph reduction significantly changes survival odds.
3. Rural roads are where New Zealanders die
Urban roads have a 0.47% fatal crash rate. Open/rural roads have 1.85% - nearly 4× higher than urban roads. The majority of crashes happen in cities, but the majority of deaths happen in the country.
Our View: This explains why comprehensive car insurance matters more for rural drivers. A minor fender incident in Auckland rarely kills anyone. The same collision at 100kph on a Waikato back road has a very different outcome.
4. Traffic signals save lives
Crashes at intersections with traffic signals have a 0.28% fatal rate. Uncontrolled intersections: 1.17%. That's a 4× difference just from having lights.
5. Motorcyclists face extreme risk
At 3.5%, motorcyclists have the highest fatal crash rate of any road user - 4.6× higher than car occupants. Of 4,483 motorcycle crashes, 169 resulted in death and 1,538 in serious injury.
Our View: Motorcycle insurance premiums are high for a reason. If you ride, comprehensive cover and ACC levy payments aren't optional - they're essential given the injury statistics.
6. What you hit matters enormously
Running off the road into water has a 6.6% fatal rate - the highest of any object struck. Trees (2.7%) and ditches (2.5%) follow. By contrast, hitting a parked vehicle is 0.3% - twenty times safer than hitting water.
Our View: Roadside hazard removal programs - clearing trees, installing barriers - aren't just beautification. They're life-saving infrastructure that improves survivability in run-off-road crashes.

Total Crashes Snapshot and Crash Severity Breakdown
Over three financial years, police attended 91,496 traffic crashes across New Zealand.
| Financial Year | Total Crashes | Deaths | Serious Injuries | Minor Injuries |
|---|---|---|---|---|
| 2022/2023 | 32,337 | 359 | 2,565 | 11,603 |
| 2023/2024 | 29,535 | 316 | 2,388 | 10,695 |
| 2024/2025 | 29,624 | 309 | 2,495 | 11,306 |
| 3-YEAR TOTAL | 91,496 | 984 | 7,448 | 33,604 |
| Change (2022/23 → 2024/25) | -8.4% | -13.9% | -2.7% | -2.6% |
Crash Severity Breakdown
Not all crashes are equal. The severity breakdown shows that the majority result in property damage only.
Know This: Only 0.96% of crashes are fatal - but with 91,496 crashes, that still means 881 fatal crash events and 984 deaths. Multiple fatalities can occur in a single crash.

| Crash Severity | Number of Crashes | % of Total | What This Means |
|---|---|---|---|
| Non-Injury Crash | 58,947 | 64.4% | Property damage only |
| Minor Crash | 25,378 | 27.7% | Minor injuries requiring first aid |
| Serious Crash | 6,290 | 6.9% | Hospitalisation required |
| Fatal Crash | 881 | 0.96% | One or more deaths |
| TOTAL | 91,496 | 100% |
Regional Vehicle Crash Data
Important context: Raw crash numbers don't tell the full story. A region with more vehicles on the road will naturally have more crashes. That's why we calculate per-capita rates - they show your actual risk of being in a crash or dying on the road, regardless of how busy the roads are.Auckland has the most crashes by volume (31% of all crashes), but when adjusted for population, the picture changes dramatically.
Know This: The West Coast has the highest crash rate per capita, but Northland has the highest fatal crash rate (2.2%), meaning crashes there are more likely to kill you. It's the combination of high crash rates and high fatality rates that makes some regions genuinely more dangerous.

| Region | Total Crashes | % of NZ Total | Crashes per 10,000 People |
|---|---|---|---|
| Auckland | 28,430 | 31.1% | 52.9 |
| Waikato | 11,186 | 12.2% | 70.1 |
| Canterbury | 9,845 | 10.8% | 50.0 |
| Wellington | 8,022 | 8.8% | 46.2 |
| Manawatū-Whanganui | 6,209 | 6.8% | 79.0 |
| Bay of Plenty | 5,762 | 6.3% | 53.9 |
| Otago | 4,573 | 5.0% | 57.1 |
| Northland | 4,311 | 4.7% | 72.2 |
| Hawke's Bay | 3,654 | 4.0% | 63.6 |
| Taranaki | 2,302 | 2.5% | 60.0 |
| Southland | 2,108 | 2.3% | 66.2 |
| Gisborne | 1,195 | 1.3% | 75.2 |
| Tasman | 974 | 1.1% | 53.5 |
| Marlborough | 923 | 1.0% | 58.6 |
| West Coast | 864 | 0.9% | 86.5 (Highest) |
| Nelson | 766 | 0.8% | 45.5 (Lowest) |
The Disproportion Problem
Some regions have far more deaths than their crash numbers would suggest:
- Marlborough: 1.0% of NZ crashes but 2.3% of deaths (2.3× disproportionate)
- Northland: 4.7% of crashes but 9.8% of deaths (2.1× disproportionate)
- Manawatū-Whanganui: 6.8% of crashes but 12.1% of deaths (1.8× disproportionate)
- Waikato: 12.2% of crashes but 18.7% of deaths (1.5× disproportionate)
- Compare this to Auckland: 31.1% of crashes but only 13.5% of deaths - crashes in Auckland are far more survivable.
Regional Death Rates Per Capita
This is where the regional differences become stark. Death rates per 100,000 population show which regions have the most dangerous roads.
Our View: The difference between Northland (around 19 deaths per 100,000 people) and Auckland (around 2 deaths per 100,000 people) reflects rural vs urban driving, road quality, speed limits, and emergency response times. These differences justify regional car insurance pricing - a Northland driver genuinely faces a higher statistical risk than an Auckland driver.

| Auckland | 31 | 1.8 | Baseline (Safest) |
| Nelson | 1 | 1.8 | Equal Safest |
| Tasman | 1 | 1.7 | Safest |
Why Some Regions Are More Dangerous
Several factors combine to make rural regions deadlier:
- Speed: Open roads with 100kph limits - at higher speeds, crashes are more likely to be fatal
- Road design: Narrow roads, lack of median barriers, roadside hazards (trees, ditches)
- Distance to hospitals: In rural areas, seriously injured people take longer to reach trauma care
- Vehicle fleet: Regional areas often have older vehicles with fewer safety features
- Tourist traffic: Unfamiliar drivers on challenging roads (West Coast, Queenstown)
District-Level Crash Analysis
Looking at territorial authorities reveals which districts have the highest crash rates per capita.
Know This: Taupo District has the highest crash rate (88 per 10,000), likely driven by tourist traffic and by SH 1/SH 5 passing through. But the Far North District combines high crash rates with high deaths - 19 deaths from 602 crashes. Urban centres like Wellington City and Tauranga have lower rates despite higher traffic volumes.

Top 20 Crash Locations in New Zealand
Our table reveals all:
| Rank | Location | Crashes | Deaths | Fatal Rate |
|---|---|---|---|---|
| 1 | Southern Motorway (Auckland) | 2,169 | 10 | 0.46% |
| 2 | SH 1 | 1,891 | 71 | 3.75% |
| 3 | Great South Road (Auckland) | 1,272 | 9 | 0.71% |
| 4 | SH 2 | 1,218 | 33 | 2.71% |
| 5 | Northern Motorway (Auckland) | 1,045 | 1 | 0.10% |
| 6 | South-Western Motorway (Auckland) | 738 | 1 | 0.14% |
| 7 | North-Western Motorway (Auckland) | 704 | 2 | 0.28% |
| 8 | Great North Road (Auckland) | 487 | 3 | 0.62% |
| 9 | Waikato Expressway | 486 | 4 | 0.82% |
| 10 | SH 5 (Napier-Taupo) | 435 | 16 | 3.68% |
For comparison: SH 1 (NZ's main highway) = 2.7 deaths per 100km over its 2,055km length
Know This: The Southern Motorway has the highest death density (45.8 per 100km) because it packs a lot of fatal crashes into just 24km. Main North Road in Canterbury is second at 43.3 deaths per 100km. By contrast, SH 1 - NZ's main highway - has just 2.7 deaths per 100km because deaths are spread across 2,055km.
Our View: Short, high-traffic roads concentrate risk. If you drive the Southern Motorway daily, you're exposed to more danger per kilometre than someone driving the length of SH 1 once a year.

| 10 | SH 10 (Far North) | 115 | 6 | 5.2 | 2.3 |
Understanding the columns:
Know This: The Northern Motorway has 55.7 crashes per km but 6.2 deaths per 100km - lots of crashes, very few fatal. Main North Road Canterbury has just 7.2 crashes per km but 43.3 deaths per 100km - fewer crashes, but when they happen, people die. That's the difference between urban prangs and high-speed rural crashes.
- Deaths per 100km shows how concentrated fatal crashes are. A short road with many deaths will score high - it means danger is packed into a small stretch.
- Crashes per km shows how busy a road is for incidents. Auckland motorways score high because they carry huge traffic volumes.

What This Means For Your Insurance
Car insurers use regional data to price risk. If you live in Northland, Waikato, or Manawatū-Whanganui, your premium may be higher than someone in Wellington or Nelson - and this data shows why. It's not arbitrary pricing; it reflects genuine differences in crash severity and death rates.
Speed Limit Analysis
Speed is the clearest predictor of crash severity. Higher speed limits correlate directly with higher death rates.
Know This: 100kph roads account for just 26.5% of all crashes but 55.7% of all deaths. The fatal crash rate at 100kph (2.02%) is 5× higher than at 50kph (0.39%).
Our View: The danger comes down to simple physics - kinetic energy increases with the square of velocity, meaning a 100kph crash has 4× the energy of a 50kph crash. This is why survivability drops so dramatically at higher speeds.

Urban vs Rural vs State Highway Vehicle Accident Analysis
Most crashes happen in urban areas, but most deaths happen on open roads. Rural roads have 36% of crashes but 71% of deaths.
Know This: Urban crashes are far more survivable. The 0.47% fatal rate in urban areas vs 1.85% in rural areas reflects lower speeds, shorter emergency response times, and better road infrastructure.

| Open/Rural | 32,730 | 35.8% | 695 | 70.6% | 1.85% (4× higher) |
State Highways vs Local Roads
State Highways carry higher speeds and through-traffic, resulting in more severe crashes.
Know This: State Highways represent 30% of crashes but 51% of deaths. The 1.56% fatal rate is more than double that of local roads (0.71%), meaning they have 2.2× higher fatal rate than local roads.

| Local Roads | 64,280 | 70.3% | 483 | 49.1% | 0.71% |
Most Dangerous State Highways
Not all state highways are equally dangerous. Here are the highways with the highest fatal crash rates (minimum 100 crashes for statistical significance).
Our View: SH26 (Morrinsville-Te Aroha) has the highest fatal rate at 5.0%. SH1, despite being NZ's main highway, has a 3.75% fatal rate - concerning, given its traffic volume. These highways warrant extra caution.

Crash Factors - What Makes Crashes Deadly
We outline five key factors below:
Traffic Control & Intersection Safety
Traffic signals dramatically reduce crash severity. The difference between controlled and uncontrolled intersections is significant.
Our View: Traffic signals reduce fatal rates from 1.17% to 0.28% - a 4× improvement. This data supports investment in intersection upgrades, even if they're unpopular for causing delays.

| Traffic Control | Crashes | % of Total | Fatal Rate | Notes |
|---|---|---|---|---|
| No Control | 61,150 | 66.8% | 1.17% | Highest risk - no intersection control |
| Stop Sign | 5,448 | 6.0% | 0.95% | Stop sign controlled intersection |
| Give Way | 16,854 | 18.4% | 0.52% | Give way controlled intersection |
| Traffic Signals | 7,597 | 8.3% | 0.28% | Lowest risk - 4× safer than no control |
Objects Struck - What Kills
What a vehicle hits during a crash dramatically affects survivability. Run-off-road crashes into certain objects are particularly deadly.
Know This: Water/river crashes have a 6.6% fatal rate - 22× higher than hitting a parked vehicle (0.3%). Trees kill 132 people over 3 years, making roadside tree removal programs a genuine life-saving intervention.

Frequently Asked Questions
How does this data relate to car insurance?
This crash data explains why car insurance premiums vary by region, age, and vehicle type. Regions with higher death rates (like Northland) will generally have higher premiums. Motorcyclists pay more because their crash outcomes are dramatically worse.
Why is Northland so dangerous?
Multiple factors contribute: high-speed rural roads, an older vehicle fleet, longer distances to hospitals, and road quality issues. The 19.4 deaths per 100,000 rate reflects these compounding risks.
Are motorcycles really that dangerous?
Yes - with a 3.52% fatal rate and 34% serious injury rate per crash, motorcyclists face extreme risk. Of 4,483 motorcycle crashes over 3 years, 1,707 resulted in death or serious injury.
Why do fine-weather crashes have higher fatal rates?
This is likely due to driver behaviour - people drive faster and take more risks when conditions seem safe. In the rain, drivers slow down and focus more. The data shows 'safe' conditions don't mean safe driving.
How does this compare to other countries?
New Zealand's road death rate is higher than Australia, the UK, and most of Western Europe as outlined here. Our rural road network, older vehicle fleet, and speed limit settings all contribute.
Why do crashes in overcast or twilight conditions seem less fatal than in bright sun?
The data shows bright sun has a slightly higher fatal rate (0.93%) than overcast (0.88%), while twilight is the riskiest at 1.12%. Drivers often overestimate visibility in "good" weather, leading to higher speeds and risk-taking. Twilight catches people off-guard during low-light transitions.
How much more dangerous are hill roads compared to flat terrain?
Crashes on hill roads have a 1.44% fatal rate - 65% higher than flat roads (0.87%). Loss of control on inclines/declines, combined with speed, amplifies severity. Many fatal rural crashes involve hills; targeted improvements like better signage, escape ramps, and speed reductions on known hilly stretches could save lives without blanket limit changes.
What impact do roadside fences or guard rails have on crash outcomes?
Hitting a fence (1.6% fatal rate) or guard rail (1.0%) is far safer than trees (2.7%), ditches (2.5%), or water (6.6%). Barriers absorb energy and prevent worse off-road outcomes.
What's the safest region to drive in?
Auckland has the lowest death rate per capita (1.8 per 100,000), followed by Tasman (1.7) and Nelson (1.8). Urban environments with lower speeds and better infrastructure are safest.
Does this data include unreported crashes?
No - this is police-reported crashes only. Minor incidents (especially property-damage-only) are under-reported. Fatal and serious injury crashes are comprehensively captured.
Why are crashes declining?
Multiple factors help contribute, including the increase in safer vehicles with ADAS, road improvements, speed management, reduced driving post-COVID, and better enforcement. The 8.4% decline over 3 years suggests road safety efforts are working.
