AS/NZS 4602 Hi-Vis Standard Explained — What NZ Employers Need to Know (2026)
AS/NZS 4602.1:2011 is the New Zealand and Australian standard for high-visibility safety garments. It defines exactly what makes a hi-vis garment compliant — not just any orange or yellow vest qualifies. Understanding this standard matters for employers legally required to provide appropriate PPE to workers in traffic management, construction, roading, and other high-visibility-risk roles. From 2026, compliance with AS/NZS 4602 will be even more critical, with stricter enforcement and updated requirements. Employers must ensure their workers are equipped with certified hi-vis gear to avoid legal liability and protect their teams.
What AS/NZS 4602.1:2011 Covers
The AS/NZS 4602.1:2011 standard sets out the minimum requirements for high-visibility garments in occupational settings. It applies to a range of items including vests, shirts, jackets, pants, and overalls. The standard ensures that garments meet specific performance criteria to enhance visibility in hazardous environments.
- Specifies requirements for high-visibility garments in occupational settings
- Applies to vests, shirts, jackets, pants, overalls
- Sets minimum areas of fluorescent background material and retroreflective tape
- Certifies performance after 25 wash cycles
Day (D) vs Day/Night (D/N) Rating
The standard differentiates between two types of hi-vis garments based on their visibility in different lighting conditions. Understanding the difference is crucial for selecting the right gear for your worksite.
- Day D: fluorescent background only — visible in daylight not at night
- Day/Night D/N: fluorescent background plus retroreflective tape — visible at night from headlights
- Retroreflective tape bounces light from vehicle headlights back to driver
- Most worksite environments require D/N for any vehicle exposure
Class 1 vs Class 2
The standard also classifies garments based on the level of visibility required. Class 1 and Class 2 have different minimum requirements, and the choice depends on the risk level of the job.
- Class 1: smaller minimum fluorescent area — lower-risk environments
- Class 2: larger minimum area plus more retroreflective tape — required for roadside work
- Road workers and traffic controllers in NZ must wear Class 2 D/N
- Most worksites default to Class 2 D/N to cover all scenarios
Background Material Colour
The background material colour is a key factor in determining the effectiveness of a hi-vis garment. Different industries may prefer different colours based on visibility and contrast.
- Yellow-green: highest daytime visibility, most common
- Orange: preferred in some industries to distinguish from traffic cones
- Check your traffic management plan for required colour
What Makes a Garment Non-Compliant
Even if a garment looks good, it may not meet the AS/NZS 4602 standard. Here are some common reasons why a garment might be non-compliant:
- No AS/NZS 4602 certification label
- Faded background material
- Damaged or missing retroreflective tape
- Worn as a mid-layer rather than outermost garment
Employer Obligations
Employers have a legal responsibility to ensure their workers are equipped with appropriate hi-vis gear. This includes providing certified garments, inspecting them regularly, and enforcing proper use.
- Provide AS/NZS 4602 certified garments at no cost to workers
- Inspect and replace when tape or fabric no longer meets standard
- Enforce wearing as outermost layer
- Match class and D/N rating to actual exposure
How to Check a Garment is Certified
Ensuring that your hi-vis gear is compliant is essential. Here’s how to verify certification:
- Look for AS/NZS 4602.1 label sewn inside garment
- Label must state Class, Rating, and manufacturer details
- No label means not certified
