Mr Noble said the area would be in for more snow showers throughout the morning.
Snow showers in the Central Plateau would clear this morning, but Mr Noble said the showers would move in tonight as the freezing level drops again.
Temperatures in the South Island were also low last night.
"There's been one or two little showers feeding in to Southland and South Otago," Mr Noble said.
The temperatures across the country would rise and the showers clear as a high over the Tasman Sea moves in across the weekend in time for the weekend, with the South Island feeling the change in weather first today.
"They're warming up a bit quicker than the rest of the country," Mr Noble said.
Hawkes Bay and Gisborne would see the last of the showers clearing tomorrow, he said.
