It was the third crash involving a car and a truck in the Waikato in four days and the second fatal accident after 45-year-old Anna Pidduck was killed on Tuesday.
Ms Pidduck's nine-year-old son Jacob Henderson is still fighting for his life in Starship Hospital while a 33-year-old woman remains in a critical condition after a similar crash near Kopu on Monday.
Mr Nicholls said a zero tolerance for anyone travelling more than 4km over the speed limit would be strictly enforced over the next two long weekends and drivers could also expect to be breath tested anywhere at any time.
"But it's not just about the high end stuff. As we've seen with two fatal intersection crashes, we're not getting the basics right so if Mr or Mrs Joe Average is seen running a red light, failing to stop at an intersection or driving without a seatbelt they too can expect to encounter enforcement action.
"As we've seen already, such intervention could prove a life saver with the potential for someone to pull out in front of you another 500m down the road."
