Earlier that day, before the holiday road toll period began, a two-car collision left one person dead and a man in his 20s in a critical condition.

Holiday makers had to take an hour-long detour through Mangawhai.
Area Commander of Waitemata North Inspector Bruce O'Brien said two vehicles crashed north of Wellsford at around 11.15am and the driver of one of the vehicles died at the scene.

However, an Auckland DHB spokeswoman said this morning he was now in a stable condition.
Auckland Rescue Helicopter Trust intensive care paramedic Russell Clarke said it was high-speed and high-impact crash that happened on a slippery blind bend.
"It took us about 40 minutes to get the guy in critical condition out of the car. We had to cut open the roof and remove the steering," Clarke said.
