Hi-Vis Workwear in NZ: More Than Just a Colour
If you work on NZ roads, construction sites, rail corridors, airports, or any environment where vehicles or moving machinery are present, chances are you're required to wear hi-vis workwear. But not all high visibility clothing is the same — and wearing the wrong type for your work environment doesn't just fail the vibe check, it can fail a safety audit and leave you exposed to genuine risk.
This guide breaks down everything NZ workers need to know about hi-vis workwear — standards, classes, what to wear when, and how to keep it compliant over time.
The NZ Standard: AS/NZS 4602
High visibility clothing in New Zealand is regulated under AS/NZS 4602:2011, the joint Australian and New Zealand standard for high visibility safety garments. This standard sets out the performance requirements for fluorescent and retroreflective materials used in workwear.
Under this standard, hi-vis garments are classified into two main categories:
- Class D (Day only): Garments that use fluorescent material only. Visible in daylight but not designed for low-light or night-time conditions.
- Class N (Night only): Garments with retroreflective tape only. Reflect light from vehicle headlights and artificial sources — not designed for daytime visibility.
- Class D/N (Day and Night): Combines both fluorescent background material and retroreflective tape. The most common requirement for most NZ worksites — required anywhere workers may be exposed to vehicle traffic in variable light conditions.
Most NZ construction sites and road work environments require Class D/N garments as a minimum. If you're unsure what's required at your worksite, check your Site Safety Plan or ask your health and safety rep.
Day vs Night Use: Choosing the Right Class
The time of day and lighting conditions at your worksite should drive your garment choice:
- Office or indoor environments with hi-vis requirements: Class D is usually sufficient
- Outdoor daytime work with no vehicle exposure: Class D
- Road work, construction, rail, or any site with vehicle or machinery exposure: Class D/N — non-negotiable
- Night work or low-light dawn/dusk shifts: Class D/N with retroreflective tape meeting the minimum tape width and placement requirements
It's worth noting that fluorescent yellow-green is the most visible colour in daylight conditions, while fluorescent orange-red performs better in low-contrast environments like forests or rural backgrounds. Most NZ worksites default to yellow-green, but check if your industry has a specific colour requirement.
Top Hi-Vis Brands for NZ Workers
The NZ market is well served by quality hi-vis brands. Here are two that consistently deliver:
Bisley Workwear
Bisley is one of the most recognised names in workwear across NZ and Australia. Their hi-vis range is comprehensive — covering vests, shirts, polos, jackets, and pants in a variety of styles suited to different industries. Bisley's hi-vis garments are well-regarded for their durability, breathability, and compliance with AS/NZS 4602. The BK6975 taped shirt and the hi-vis fleece jacket are particularly popular with NZ tradies and road crews.
Tuffviz
A brand purpose-built for demanding NZ worksite conditions. Tuffviz specialises in high visibility workwear that prioritises rugged construction alongside compliance. Their gear is designed to handle hard wear, repeated washing, and the unpredictable NZ climate — without losing its visibility rating prematurely. If you're in a heavy-duty environment, Tuffviz is worth a look.

Washing and Maintaining Hi-Vis Garments
This is where many workers (and employers) slip up. Hi-vis garments degrade over time and with washing — and a faded, dirty, or worn hi-vis vest is no longer compliant, even if it's technically the right colour.
Here's how to keep your hi-vis gear performing:
- Wash inside out — reduces abrasion on the fluorescent face fabric and retroreflective tape
- Use a gentle, non-bio detergent — harsh detergents and bleach degrade fluorescent dyes faster
- Wash at 40°C or lower — high temperatures damage both the fluorescent fabric and the adhesive/stitching on retroreflective tape
- Avoid tumble drying — air dry where possible. Heat accelerates degradation of both the material and the tape
- Don't dry clean — solvents used in dry cleaning destroy fluorescent properties
- Inspect regularly — check for fading, tears, contamination (especially oils or grease, which can permanently reduce visibility), and retroreflective tape that's peeling or cracking
- Replace when degraded — a hi-vis garment that's faded, stained, or has damaged tape is no longer doing its job. Retire it
Most quality hi-vis garments will maintain compliance for 50+ washes if cared for correctly. Keep a rough count, or use a marker pen to note the purchase date inside the collar.
Hi-Vis Beyond the Vest: Full Compliance Coverage
Many sites now require more than just a hi-vis vest — especially on higher-risk worksites and roading jobs. Consider whether you need:
- Hi-vis pants or shorts: Required on some road and rail sites. Increases your visible profile significantly, especially from vehicle cab height
- Hi-vis jacket or rain jacket: If you're working in wet conditions, a hi-vis waterproof jacket keeps you visible and dry simultaneously
- Hi-vis polo or shirt: Replaces a vest for warmer conditions while maintaining compliance
- Hi-vis hard hat stickers or bands: Useful for improving visibility on top — not a substitute for compliant clothing, but a useful addition
Stay Compliant, Stay Safe
Hi-vis workwear is simple in concept but important to get right. Buy garments that meet AS/NZS 4602, choose the right class for your work environment, and maintain them properly so they stay compliant over time.
