What Is VLT (Visible Light Transmission)?
Visible Light Transmission (VLT) is how much light can pass through the glass with tint film on. Higher % = lighter. Example: 35% VLT is moderately dark; 70% VLT looks almost clear.
- 5% VLT = Nearly black (extremely dark)
- 35% VLT = Moderately dark
- 70% VLT+ = Nearly clear
In NZ, the Land Transport Rule: Glazing, Windscreen Wipe and Wash, and Mirrors 2007 governs this. You can find the full legal framework on the NZTA website.
Legal Tint Limits For Window Tint Laws NZ (2025 Update)
According to NZTA regulations, the legal limits are:
| Window | MA Vehicles (Sedan, Hatchbacks, Wagons, Some SUVs) | NON-MA Vehicles (Utes, Vans, Some SUVs) |
|---|---|---|
| Front Side Windows (Driver & Passenger) | ≥35% | ≥35% |
| Rear Side Windows | ≥35% | No Limit |
| Rear Window (Back Windshield) | ≥35% | No Limit |
| Front Windscreen | No tint allowed except anti-glare band (see note) | No tint allowed except anti-glare band (see note) |
However, some modern cars’ rear factory glasses came pre tinted (built in the glass) and usually the UV rejection is not high. We usually recommend install a ceramic tint on top to get the extra UV rejection and heat rejection. Contact us here for a quotation.
Why Are There Legal Tint Limits in NZ?
The NZTA enforces these rules to:
- Improve road safety (dark tints reduce visibility, especially at night)
- Help law enforcement (officers need to see inside vehicles)
- Prevent accidents (excessive tinting can obscure hazards)
WOF inspectors use VLT meters to check the percentage. If your tint is too dark, you’ll be asked to remove it before passing the inspection. Or worst, you won’t be able to pass your WoF.
Pro Tip: If you’re unsure about your current tint, contact us for verification.
