1.2 WoF Validity, Reference Dates & Label Control

Calculate the WoF from the reference date

A WoF expiry problem has two stages: determine the reference date, then apply the correct period for the vehicle. Do not simply add a year to the inspection date.

Stage 1: choose the reference date

Use the pass date when the vehicle has no current WoF, its WoF has expired, it is new and unregistered, or it is returning after a pink or green sticker or a formal revocation. For a vehicle with a current WoF:

The more-than-14-day rule preserves only 14 days from the new inspection; it does not use the full old expiry, and it does not reduce the reference date to the pass date.

Stage 2: apply the current duration

For inspections conducted on 3 October 2026, the current VIRM rules apply:

• a new, previously unregistered vehicle generally receives three years from the reference date;
• if that new vehicle receives a WoF within its first two years, expiry is the third anniversary of its first registration;
• a vehicle first registered anywhere on or after 1 January 2000 generally receives 12 months;
• a vehicle first registered before 1 January 2000 that is less than 40 years old receives six months;
• a vintage vehicle manufactured on or after 1 January 1919 and at least 40 years old receives 12 months; a veteran vehicle manufactured before 1919 also receives 12 months.

Always confirm exceptions in the current Introduction section. “Pre-2000 means six months” is incomplete because the vintage and veteran rules matter.

Worked example

A 2015 passenger car passes on 10 October and its current WoF expires on 30 October. The old expiry is 20 days away, so the new reference date is 24 October—14 days after the pass. The 12-month period is measured from 24 October. If the old WoF instead expired on 20 October, only 10 days away, the existing 20 October expiry would be the reference date.

Completing and controlling the label

After a pass, the certification record and physical label must agree. Select the correct label year, punch the month and year as directed, and complete the reverse with the inspecting organisation, vehicle registration, inspector authority number, and full expiry date. Affix the label to the inside of the windscreen on the same side as the steering wheel, where it is visible as required and does not obstruct the driver’s vision.

Keep labels secure. Spoiled or cancelled labels and reconciliation records are controlled certification material; follow the VIRM process rather than improvising disposal. A replacement label may be issued only after confirming the underlying current WoF record and the vehicle identity. The inspecting organisation may charge a reasonable replacement fee, but the VIRM does not establish a universal $10–$15 statutory cap.

A failed early inspection does not, by itself, erase a still-current WoF. The WoF ceases through expiry, revocation, or the other specified events. However, once an inspection identifies non-compliance, the vehicle may be operated only as the law permits—for example, when it is safe to drive for repair or recheck—not treated as though the discovered faults are irrelevant.

Date-sensitive change alert

NZTA has announced inspection-frequency changes effective 1 November 2026. Those future rules must be applied only from their effective date. On an assessment, first establish the scenario date and consult the version of the VIRM in force then. This prevents a common open-book error: locating a valid announcement but applying it too early.

Prevent date and label errors

Write the three dates separately on scratch paper: pass date, existing expiry, and selected reference date. Calculate the difference before choosing the rule, then add the vehicle’s period. This prevents silently switching from “expires within 14 days” to “vehicle inspected within 14 days.” Finally, compare the calculated expiry with VIC/LATIS before punching the label. If the electronic record and your calculation disagree, stop and resolve the cause; never alter a label to disguise a system-entry error.

A duplicate label reproduces a valid existing certification—it does not extend the WoF, change its reference date, or cure an identity discrepancy. Verify registration/VIN and current status first, record issuance through the approved process, and maintain label stock control.
