Snow has blanketed the deep south, falling down to sea level in Dunedin and Invercargill and forcing the closure of Queenstown Airport.
The heavy snow disrupted flights into the resort town on the first Monday of the school holidays, with Queenstown having three to four centimetres of snow this morning, a MetService spokesperson told 1 NEWS.
State Highway 94 to Te Anau has reopened, with the cars who were trapped having been freed.
The wind chill felt like -20 in some places with freezing temperatures and strong winds, a NIWA forecaster told RNZ.
