Southerly snap: More snow, hail and winds coming

The Desert Road and Rimutaka Hill Road are closed by snow tonight, as the cold blast makes its way up the country.

Further south, roads and schools closed and mail deliveries were cancelled today due to icy roads.

Air New Zealand said thunder and lightning delayed flights at Auckland airport, snow had affected services to and from Dunedin, and heavy snow showers caused widespread cancellations at Queenstown.

Alexandra had seen one of the heaviest falls in years, while snowfall in Kingston, Otago, exceeded 30cm, WeatherWatch analyst Richard Green said.

Areas of Canterbury and Wellington received light snowfall and cold southerly winds today with hail and sleet.

Chains were required in most places in the south, and motorists were warned to take extra care particularly over the Lewis, Porters, Arthur's and Lindis Passes.

Some Dunedin schools were closed today and bus services cancelled due to snow, and mail deliveries were halted across most of Otago.

The conditions forced two outpatient clinics to close at Dunedin Hospital.

Heavy snowfalls were forecast for Taihape and the central North Island high country, MetService said, with 25-35cm accumulating by morning.
