Her death was followed by two fatalities in Canterbury.
A woman was killed when she was thrown from a motorbike and into the path of oncoming traffic on Sunday. The same day, Andrew Lawrence Orr, 23, was killed on a country road in north Canterbury after his four wheel drive vehicle ended up down a bank on Lees Valley Road in Oxford.
Canterbury police search and rescuers led an operation to locate Mr Orr after the driver following his vehicle lost sight of him.
It took more than four hours to locate Mr Orr's body after his car was found down the bank.
Canterbury police investigations are continuing and the death has been referred to the coroner.
Mr Orr's family has thanked Canterbury police for their support following the tragedy.
In the most recent fatal crash, a man died after a car veered off the road, hit rocks and flipped into mangroves at Mangawhai, Northland, early yesterday morning.
Raymond Frost, 42, of Mangawhai, died at the scene on Insley St, about 100km north of Auckland, after the 12.40am crash, police said.
Mr Frost's family are being supported by Police and Victim Support.
An investigation into the incident is still on going.
The holiday toll is still provisional and several people remain in hospital with potentially life threatening injuries, so the number could still rise.
Mr Cliff said it was important to remember that road deaths were "just the tip of the iceberg" when it came to road trauma.
"There will be about a hundred odd people who have been injured, many of them will be in the country's hospitals and some with life-long disabilities."
Mr Cliff said police were still investigating the causes of the fatal crashes, but time and time again the same factors were usually responsible.
"The big issues ... from a behavioural perspective are travelling too fast ... failing to pay attention, drink driving and failing to wear safety belts."
Most New Zealand drivers were getting the message about good driving practice but some were still struggling.
"There's a minority who just can't get their heads around the relationship between travel speed and injury outcome," Mr Cliff said.
"We never want to see anyone killed or seriously injured so what we continue to look at is long term trends."
Mr Cliff said trends were positive when it came to drink driving and speeding, but New Zealand's number of deaths per 100,000 were still much higher than other western countries.
"[It's] still at twice the rate of the best performing countries.
"If you go to Sweden, the Netherlands, they're at about three deaths per 100,000 - we're sitting at just over six, so that gives you a relative sense of our performance."
Mr Cliff said a safe system, where speed and drink driving compliance was heavily monitored, combined with safer vehicles and better driving habits, was the only way to reduce the road toll to zero.
Part of the safer system could include reducing the speed limit along country roads from 100 to 70 or 80.
"The speed limit [should be] consistent with what the design for the road is."
Mr Cliff said currently many of the country's winding country roads were not suited for driving at 100km/h.
The official Queen's Birthday holiday road period ran from 4pm on Friday to 6am today.
