# How does the NZTA sync work?
## Argus checks NZTA's database every Tuesday night for WoF, CoF and registration status, and looks up a new registration overnight when you enter one on an asset profile.
If your WOF, COF or registration details aren't showing correctly on your compliance table, it's usually because the weekly overnight sync with NZTA hasn't run yet, or the record has been out of date for too long for automatic sync to keep checking it.
**Also known as / customers also ask:** NZTA sync, WOF not updating, rego not showing, NZTA database sync, compliance not syncing, why is my WOF wrong
## What does the NZTA sync do?
The NZTA sync keeps two parts of the Argus Dashboard aligned with NZTA's database: your asset profile details, and your Fleet Management \> Compliance table.
## How does the sync work on my asset profile?
In **My Assets \> Profile**, once you enter a vehicle's registration, Argus looks up the NZTA database and updates the fields on the profile page from NZTA's data. This lookup runs overnight, so a newly entered registration's details typically appear the next day rather than instantly. Every time you change a vehicle's registration in its profile, all the rego, WoF/CoF and vehicle detail fields are cleared and refreshed from the NZTA sync — so double-check the registration is correct before saving a change.
## How does the sync work on my Compliance page?
For date-based compliance — your WoF, CoF and registration expiry — Argus checks the NZTA database every Tuesday night. If a record is due to expire within the next 28 days, the Compliance table shows that vehicle as requiring attention and highlights the relevant field in orange. If the same check finds your compliance issue has been resolved — for example, you've got a new WoF or renewed your registration — the highlight reverts to blue. If a compliance issue lapses without being resolved, the field turns red.
## When does the sync stop looking up a record automatically?
Argus continues checking an overdue WoF, CoF or registration for up to 28 days after it lapses. After that, automatic lookup stops as a safeguard, and you'll need to update the record yourself — either directly on the Compliance page or through a Check Sheet.
## How do I know it worked?
The relevant field on your Compliance table changes colour — from orange or red back to blue — once NZTA's records confirm the issue is resolved and the next sync has run.
## What if it doesn't work?
**A field stays red after you've renewed:** allow until the next Tuesday night sync before assuming something's wrong.
**A field has stayed red for weeks:** if it's been overdue more than 28 days, automatic sync has stopped for that record — enter the correct details manually.
