The map needs JavaScript, the counts below still stand.

Each dot is one crash in the record, coloured by the worst injury in it. Click a dot for what the Crash Analysis System (CAS) knows, the roads, who was involved, what the day was like, and how often that corner appears.

How often
2025 saw 689 injury crashes, about 36% below the 2007 peak of 1,069.
Crashes that hurt somebody, a year taller is worse, a column opens its year
Crashes in which at least one person was hurt. 2026 is still being filed and is left off, 465 injury crashes are already on record for it.
The whole record, by severity 44,833 crashes
Severity is the worst injury in the crash; the counts beside each row are people. Reported damage-only crashes rise and fall with how willing people are to fill in a form, the record holds them, the trend lines above do not count them.

Where it keeps happening
The corners and roads the record names most, since 2016. A corner needs both streets named to appear in the first list; a mid-block crash names only its road.
Corners worst first
Roads worst first
16,108 of the 16,197 injury crashes on record name a corner, two roads in the report; the other 89 name only their road.
A row opens the spot on the address page, what stands there now, and everything else the record holds for it.
Every road pairing, ranked and paged: the pairings the record keeps: one page per crossing.
Who it happens to
On foot, on a bike, on a motorbike, the road users with no shell around them. Each tile opens the map filtered to that mode.
"Involving" counts the crash, not the blame, a bicycle in a crash is a bicycle in a crash whoever caused it, and one crash can carry several of these. A tile opens the map filtered to it. CAS does not publish causes at all.
The rest of the record
What the record also says, where inside the city crashes land, and the limits on the roads they happened on.
By suburb since 2016
By the speed limit injury crashes, and the share that killed
The same rows, the other way, for every hundred crashes at the limit, how many killed somebody. The limit is the road’s own, not the speed the driver chose.
The count bar is where the crashes are; the rate is where the harm is. A crash on a 100 km/h road kills somebody about 4.3× as often as one on a 50 km/h street, 31 killed in 732 crashes against 118 in 11,897 crashes.
The day of it
What CAS records about each crash beyond the toll, the thing it struck, the weather it happened in, what held the crossing and the rest of the fleet on the road.
What they hit injury crashes
A crash can hit several things, most hit nothing at all.
The weather it happened in injury crashes
A second condition rode some of them, strong wind on 186, frost on 177.
How the crossing was controlled injury crashes
The control CAS recorded at the spot: what held the traffic, not which rule was broken.
The vehicles on the day injury crashes
The rest of the fleet, the bikes, motorbikes and trucks are counted with the road users above.

From NZTA’s Crash Analysis System, the police-reported record, shared under CC BY 4.0, refreshed here 6 October 2026. CAS receives a crash weeks after it happens, once the police report is filed, so the most recent months are always incomplete. The record carries no date finer than the year, no causes and no blame, and a pin is where the report put the crash, a corner’s cluster can sit a few metres off the kerb. Damage-only reporting especially depends on people choosing to file, so it undercounts more than the harm figures do.
