New Zealand Bans Studded Tyres, Sets 1.5mm Floor, 2026

New Zealand bans studded tyres outright, nationwide, with no regional exceptions. Its legal tread minimum is set at 1.5mm, a touch below the 1.6mm figure used almost everywhere else in this guide. There’s no winter tyre mandate, and all-season tyres are accepted without restriction.

Whether you are touring New Zealand by campervan or renting a car for a few days, most fines here are avoidable with five minutes of preparation.

Tyre Law Summary for New Zealand

Winter Tyre Rules in New Zealand

Winter tyres are not mandated in New Zealand. The climate across most of the country is warm enough that summer or all-season tyres are the practical choice year-round. Rain and wet roads are a bigger concern than cold for tyre safety here.

Minimum Tread Depth in New Zealand

In New Zealand, the legal minimum tyre tread depth is 1.5 mm, measured across the central three-quarters of the tread width around the full circumference.

Safety organisations recommend that drivers in New Zealand replace tyres at 3.0 mm rather than running them down to the legal limit. The difference in wet braking at 80 km/h:

Tread inspection in New Zealand: look for the TWI bars moulded into your tyre grooves. When these are flush with the tread surface, you are at 1.5 mm — replacement is overdue.

Studded Tyres in New Zealand

Studded tyres are prohibited in New Zealand. Metal studs damage road surfaces, and the cost of repairing stud-damaged asphalt is substantial. Modern friction winter tyres with silica-enriched compounds and 3D sipe technology provide comparable ice grip without the road damage.

All-Season Tyres in New Zealand

All-season tyres with the M+S marking are accepted in New Zealand. For drivers who prefer not to switch tyres seasonally, they offer a practical middle ground — adequate in mild winters and acceptable in summer heat, though not optimal in either extreme.

Penalties for Tyre Violations in New Zealand

Tyre violations in New Zealand carry fines and may affect your licence. For context on enforcement severity: a seatbelt violation costs NZD 150 (approx. EUR 85), so expect tyre offences to be taken at least as seriously.

Visitors take note: New Zealand enforces tyre rules on foreign-plated vehicles just as strictly as on domestic ones.

Tyre Choice for New Zealand’s Climate

New Zealand has varied climate from tropical to temperate. This means tyre needs vary significantly by region:

• Lowland/coastal areas: warm and humid year-round — prioritise wet grip and heat resistance
• Highland/southern regions: cooler temperatures may warrant all-season tyres with the M+S marking
• Rainy season: heavy downpours are the primary tyre hazard — adequate tread depth is non-negotiable
• Long distances: New Zealand is large, and extended drives at speed increase centre-tread wear. Check tyres before any trip over 300 km

Road Conditions and Tyre Wear in New Zealand

New Zealand has a well-maintained road network. Tyre wear tends to be predictable and even on main roads. Urban stop-and-go traffic causes shoulder wear, while longer highway stretches wear the centre. Regular rotation (every 8,000–10,000 km) keeps wear even.

New Zealand drives on the left. If your vehicle was originally configured for right-hand traffic, weight distribution is slightly different, which can cause uneven wear patterns over time.

How New Zealand’s Tyre Laws Compare to Neighbours

If you are driving across borders from New Zealand, tyre regulations may change at each crossing:

• Australia: Winter tyres not required. Tread: 1.5 mm. Studded: prohibited.
