For an ordinary passenger car classified as MA under New Zealand’s vehicle rules, NZTA's in-service inspection manual requires transparent film on front side windows to leave at least 35% overall visible light transmittance (VLT). The same minimum applies to transparent rear-window film on class MA vehicles, with specific exceptions for stretch limousines and body-transfer vehicles. Rear overlays also require exterior mirrors on both sides. This guide focuses on ordinary MA cars.
Identify the vehicle class first
Confirm the car's recorded vehicle class; an SUV label alone does not establish it. Ask a Warrant of Fitness (WoF) inspection provider if the vehicle class is unclear.
The manual lists separate rear-overlay provisions for other vehicle classes and for stretch limousines and body-transfer vehicles. Do not apply that allowance to an ordinary car merely because it is advertised as an SUV. Any vehicle with film applied to a rear window needs exterior rear-view mirrors on both sides.
Film is different from original equipment
Overall VLT includes the existing glazing and any overlay. A film product's percentage is therefore not the finished window's result. The in-service inspection manual, section 5-1, lists front-side VLT below 35% as a rejection condition and sets the same overall minimum for transparent rear overlays on ordinary MA cars.
By contrast, the entry-certification manual, notes 1 and 3, says the 35% rear and rear-side limit for MA vehicles applies to modified glazing. Unmodified original-equipment glazing may pass below 35% if it carries an approved standard or trade-name marking. The applicable marking requirements also depend on manufacture date: note 1 recognizes approved trade-name markings as evidence for vehicles manufactured before January 1, 1991. This is a conditional inspection provision, not a general permission to add dark film over privacy glass.
The windscreen has different rules
The in-service manual requires at least 70% windscreen VLT. That does not authorize a full-windscreen film installation.
Table 5-1-6 in the in-service manual permits a transparent top band no lower than the original sun visors fully folded toward the windscreen. Print must stay within 100 mm of the top edge, measured as note 4 specifies. Its lower stoneguard provision excludes classes MA and MC.
More than a meter reading
The in-service manual also checks visibility, defects, dazzling mirrored effects and effects on the high-mounted stop lamp. Its note 8 describes a 5% VLT-reading tolerance for variation in films and meters. This guide does not convert that inspection tolerance into a lower installation target or a guaranteed pass.
Confirm the class, distinguish original glass from added film, measure the finished windows and check mirror and visibility requirements. Standards markings, entry certification and an in-service WoF assessment address different questions; none should be reduced to a film-label percentage.
