Police have issued a warning to motorists to take care on the roads due to a number of incidents where cars have slid because of ice over the long weekend.
Rotorua police Senior Sergeant Malcolm Collins said police had received a number of calls throughout the long weekend due to cars losing control on black ice.
"Police were flat out this morning dealing with vehicles losing control on black ice," he said yesterday.
Mr Collins said police believed ice was a factor in the single vehicle crash that killed a 51-year-old man from Rotorua on State Highway 38 on Sunday.
He said State Highway 5, both north and south of Rotorua, was prone to black ice and drivers needed to take care in those areas.
"It's obviously found in the areas where the sun's not hitting the road and anywhere surrounded by forestry."
He said drivers should look out for shadows across the road, especially on corners.
"When you're driving in icy conditions give yourself plenty of space when you are following someone else so you have enough time to stop safely.
"Reduce your speed prior to corners and gently accelerate out of corners, not hard planting the foot."
There had been 11 deaths in the long weekend's road toll for New Zealand as of Monday evening.
Another single vehicle crash happened on State Highway 38 near Kaingaroa Forest yesterday.
The driver was taken to Rotorua Hospital with minor injuries and a Rotorua Hospital duty manager told the Rotorua Daily Post yesterday the person was in a stable condition.
MetService meteorologist Emma Blades said Rotorua only got above zero degrees at 10am yesterday. She said the forecast for today was sitting at a low of 2 degrees.
"But that means it could be dropping to below freezing so there could be ice around again, but on Tuesday night the temperatures are picking up and there will be a bit of cloud cover to trap in some of the days heat."
She said on Wednesday it would be cloudy again with showers and then Thursday and Friday looked wet with the temperature picking up again.
"It looks like Rotorua will be moving from the danger of ice to possible surface flooding."
