Quick answer: AS/NZS 4602.1 compliance comes down to three things: the right combination of fluorescent background colour and retroreflective tape for the garment's class, tape that's still genuinely reflective (not just present), and matching day-only versus day/night rated garments to how your team actually works. A garment that passed inspection new can silently fall out of compliance after enough washes, sun exposure, and general wear.

Hi-vis is one of those things everyone assumes is sorted the day it's issued and rarely checks again. That's a problem, because AS/NZS 4602.1 compliance isn't a one-time purchase decision — it's a condition that degrades, and a business is responsible for what's actually being worn on site, not what was compliant when it left the packaging. Here's what the standard actually requires, and how to keep your team genuinely covered rather than just technically issued gear.

1. What AS/NZS 4602.1 actually requires

The standard sets requirements for two things working together: a fluorescent background colour (orange, yellow, or yellow-green) that stands out against typical work environments, and retroreflective tape that bounces light back at night or in low visibility. Garments are then classed by how much of each they provide — Class D (daytime only) or Class D/N (day and night). Neither the colour nor the tape works alone; a bright shirt with no tape isn't night-compliant no matter how vivid the colour is, and worn-out tape on a bright shirt isn't compliant either, even though it still looks fine from a distance. See our Day vs Night-Rated Hi-Vis guide for a full breakdown of the two classes.

2. Day-only vs day/night rated: which one do you actually need

This is the distinction most businesses get wrong — not because they choose badly, but because they don't choose at all and just buy "hi-vis." A non-taped garment is genuinely fine for daytime-only outdoor work where visibility is never an issue. The moment there's any low-light, dawn/dusk, indoor-with-poor-lighting, or night component to the job, only a taped, day/night rated garment is compliant.

3. How hi-vis garments lose compliance over time

Compliance isn't permanent. Washing gradually reduces retroreflective performance — most tape has a rated number of wash cycles before it can no longer bounce back enough light to meet the standard, even though it still looks reflective under normal light. UV exposure fades the fluorescent background colour, particularly in fleet vehicles left in direct sun. And simple wear and tear — cracking, peeling, or partially detached tape — is the most common failure, because a garment can look perfectly fine from a few metres away while its tape has effectively stopped working.

4. How to audit your team's existing hi-vis stock

Run this as an actual scheduled check, not a one-off glance: inspect tape for cracking, peeling, or dulling under direct light rather than just checking it's there; check the fluorescent colour hasn't visibly faded compared to a new garment of the same style; note how many wash cycles a garment has likely had if it's been in rotation for a year or more; and replace on a schedule tied to actual wear, not just when something looks visibly damaged. A stocktake once or twice a year, timed before a seasonal bulk order, catches most of this before it becomes a compliance gap. Our Winter Workwear Checklist covers exactly this ahead of the cold season.

5. What to look for when buying replacements

Confirm the garment is explicitly labelled to AS/NZS 4602.1 and check which class it's rated for — don't assume a bright colour alone means compliant. Match the class to how the job is actually worked, not how it's worked on a good day. And keep a small buffer of taped, day/night rated garments on hand for anyone whose hours or site conditions change unexpectedly, rather than discovering a gap mid-shift.
