Snow closes Desert Road as wintry blast sweeps across country

State Highway 1 Desert Road is closed because of snow between Rangipo and Waiouru until further notice.

A wintry blast is sweeping across the country, bringing below-freezing temperatures.

NZTA said a detour around the Desert Road is available and will add at least 40 minutes to motorists journey time.

For northbound traffic turn left onto State Highway 49, right onto SH4, right onto SH47, right onto SH46 and then left back onto SH1. Southbound travellers should do this in reverse.
