New Zealand winters are cold, wet and windy — a tough combination for anyone working outdoors. Cold, damp conditions don't just make for a miserable day; they sap your concentration, slow your hands and, at the extreme, cause cold stress and hypothermia. Dressing for it properly keeps you safe and productive.
Dress in three layers
The layering system is the key to warmth you can regulate:
| Layer | Job | Best fabric |
|---|---|---|
| Base | Wick sweat off skin | Merino or synthetic (never cotton) |
| Mid | Trap body heat | Fleece or wool |
| Outer | Block wind & rain | Windproof / waterproof shell |
Shop fleece mid-layers, wet-weather outerwear and merino base layers. For a full winter kit list, see our winter workwear guide.
Don't forget the extremities
You lose a lot of heat through your head, and cold hands are a real safety hazard when you're handling tools. A warm beanie (or a merino cap under a helmet), insulated gloves and warm, dry socks make a big difference. Keeping your feet dry matters most of all — see our boot-drying guide.
Recognise cold stress early
Watch yourself and your crew for heavy shivering, cold pale skin, and fumbling or clumsiness — the early signs of cold stress. If shivering stops and someone becomes confused, drowsy or slurred, treat it as hypothermia and a medical emergency: get them warm and dry and seek help. Take regular warm breaks, keep hot drinks and food up, and swap out of wet gear as soon as you can.
Frequently asked questions
What is cold stress at work?
Cold stress is what happens when your body can't keep its core temperature up in cold, wet or windy conditions. It ranges from cold hands and reduced dexterity through to hypothermia. Wind and rain make it far worse than air temperature alone suggests.
How should I layer for outdoor work in winter?
Use three layers: a moisture-wicking base layer (merino or synthetic, not cotton) to move sweat off your skin, an insulating mid layer like fleece to trap warmth, and a windproof, waterproof outer layer. You can add or shed the mid layer as you warm up.
What are the warning signs of hypothermia?
Early signs are heavy shivering, cold pale skin and clumsiness. As it worsens, shivering may stop and the person becomes confused, drowsy or slurred — that's a medical emergency. Get them warm and dry and seek help immediately.
Why shouldn't I wear cotton in the cold?
Cotton soaks up sweat and rain and holds it against your skin, which draws heat away and chills you fast. Merino and synthetic base layers wick moisture away and keep insulating even when damp.
