The new system has been introduced by the NZ Transport Agency for the southern alpine passes, and will limit the movement of cars, even with chains, when there's snow.

The agency is tightening up on letting motorists cross Porters and Arthur’s passes (both SH73).
But this winter, the road would be closed while graders clear the snow and lay down grit, and vehicles would only be allowed to pass once it was safe.
The Porter Heights, Mount Cheeseman, Craigieburn, Temple Basin and Broken River skifields could all be affected by the changes.
