How to fit snow chains on your wheels: A South Island guide

Why are snow chains important in the South Island?

Snow chains dramatically improve traction on snow and ice, reducing the risk of accidents and ensuring you can safely navigate winter roads. In many South Island alpine areas, snow chains are strongly recommended, and in some places, legally required.

Where are snow chains required in the South Island?

Milford Road (SH94):

It is a legal requirement for all vehicles travelling between Te Anau and Milford Sound to carry snow chains from June through November, regardless of the forecast.

Authorities conduct regular checks, and fines apply if you do not have chains. Only fit chains when instructed by road signs or when snow or ice is present.

Queenstown and the Lakes District:

You must carry snow chains if directed by authorities, especially on roads to ski fields.

Fines of NZD150 apply if you do not have chains when required. Ski field operators may also require chains as a condition of entry.

Other Alpine Roads:

Arthur’s Pass (SH73), Lindis Pass (SH8), Crown Range Road, Porters Pass (SH73), and Burkes Pass (SH8):

Chains become mandatory when snow or ice is present or when directed by authorities. Always check road conditions before you travel. Ignoring these requirements can result in fines or being turned back by authorities.

Step-by-Step: Fitting snow chains?

What You’ll Need

– Correctly sized snow chains for your vehicle’s tyres.

– A flat, safe area to park off the road.

– A torch or headlamp (for fitting chains in low light).

Please note:
This guide is for demonstration and educational purposes. Snow chains should only be fitted and used on snow or ice, as directed by road signs and authorities. Do not use snow chains on clear roads; doing so can cause damage to your vehicle and the road surface.

1. Park safely

Find a flat, safe spot off the road.

Engage your parking brake and turn off the engine.

2. Prepare the chains

Lay the chains out flat and untangle them.

Check that all hooks and fasteners are in good condition.

Make sure the entire set of chains is properly positioned:

The inside fastener should be as close as possible to the inner side of the tyre, and the outside fastener should be positioned at the level between the side of the tyre and the alloy wheel.

5. Tighten and check

Use tensioners to remove slack.

Drive forward a short distance (10–15 metres), then stop and recheck the chains for tightness.

6. Drive Cautiously

Keep your speed under 40 km/h when using chains.

Remove chains as soon as you’re back on clear roads to prevent damage.

Please note:
Different snow chains may require different fitting methods. If you’re using a rental vehicle, ask the rental company for instructions on how to fit the chains. If you have your own chains, read and study the manual before fitting them.

South Island travel tips

Check road conditions:
Always check the NZTA website or local road updates before you travel, as conditions can change rapidly.

Carry chains as a precaution:
Even if not required, having chains on hand is recommended for high country or alpine travel.

Follow signage and instructions:
Roadside signs and staff will indicate when chains must be fitted or carried.

Practice at home:
Try fitting your chains in a safe, dry environment before your trip to avoid stress in cold or snowy conditions.
