The incident was attended by police, fire and ambulance officers from Napier, about 40 minutes away.
Late last night, conditions on at least one corner in the immediate area were being reported by police to be "extremely slippery."
The Ministry of Transport's official Queen's Birthday holiday road toll period started at 4pm.
However, hopes of a fatality-free weekend dashed less than two hours later in the South Island with one person dead and seven injured after a four-vehicle crash on State Highway 1 near Dunedin.
The road toll for Queen's Birthday Weekend last year was five, but none were in Hawke's Bay, although emergency services attended four crashes in the region.
The weekend road toll period ends at 6am on Tuesday.
