From 1 November 2026, NZTA will change how often light vehicles need a warrant of fitness and will add driver-assistance warning lights to the inspection checklist.
The warrant of fitness is changing in two ways. NZTA has confirmed that WoF and CoF A frequency changes take effect on 1 November 2026. From the same date, inspectors will also check modern driver-assistance systems.
The frequency change gets the headlines. For owners of newer cars, though, the ADAS check could matter more.
Who the Frequency Changes Affect
The WoF changes cover all light vehicles except agricultural vehicles. The CoF A change is narrower and applies only to light rental service vehicles.
Nobody needs to rush out for an early inspection. Current WoF and CoF A expiry dates stay as they are. Each vehicle moves to the new schedule at its next inspection.
There is one wrinkle. Vehicles aged 4–7 years and 7–14 years will switch to the new frequency at different times. NZTA says this spreads WoF volumes across the years so testing stations don’t get swamped. NZTA has published a table showing the timing for each age group. Owners in those brackets should check it rather than assume their car follows the standard rule.
Warning Lights Now Part of the Check
This is the more interesting part. From 1 November, a WoF or CoF A inspection must confirm that no warning or malfunction indicators are showing for any advanced driver assistance system (ADAS). This covers systems that fully or partially control steering or movement.
NZTA cites Lane Keep Assist and Automatic Emergency Braking as examples. Both can steer or change speed without input from the driver. The agency sorts these features into four categories. It also stresses that its examples are not a complete list.
If a warning light is showing, the inspector must record which ADAS category failed in the check sheet notes. A new fault code under “Internal Inspection” supports this. That ambiguous orange dash light you’ve been ignoring is now a WoF issue.
What Inspectors and Owners Should Expect
The changes are being rolled out in stages:
- From 1 October 2026: WoF label books for the new frequencies can be ordered.
- Mid-October: NZTA will send out previews of the upcoming changes.
- 1 November 2026: Updated VIRM content and an ADAS technical bulletin will be published.
Updated check sheets will be available through Bluestar soon. The check sheet specification document has already been revised.
Higher Fines for Drivers
NZTA says drivers will carry more responsibility for keeping their vehicles safe under the new frequencies. To reflect that, some fines will increase. The source material does not list the new amounts.
Taken together, the trade-off is clear. Fewer routine inspections put more of the burden on owners. At the same time, the WoF itself is being updated for cars that steer and brake for themselves.
