It was the very next year that 500 was passed with 559 deaths in 1965, 600 was passed with 655 in 1970, 700 was passed with 713 in 1972, and just the next year that New Zealand set its tragic record. The toll had more than doubled in 10 years.
If we're going for the record, there is only one that is worth going for, albeit unlikely to be achieved and impossible to beat. It's the big-fat Zero prior to the advent of the automobile.
Cars were first imported in 1898, the first fatality in New Zealand said to have involved a motor vehicle was when Claude Smith was thrown from his horse-drawn trap when the animal was startled by an oncoming car in Christchurch in 1902, a motorcyclist died in an incident with a train in Dunedin in 1905, and a South Canterbury farmer's wife died when the car she was driving crashed in 1906.
The most common contributing factors have changed over the 120 years since William McLean imported his Benz automobiles in 1898 and the first fatalities of the 20th century, whether it be speeds, alcohol (including late-night closing at pubs which were built with carparks the size of football fields), and the increasing number of vehicles on the roads. Add to them any number of distractions, including cellphones, drinking coffee on-the-go or munching takeaways at the wheel.
That leads to the one constant. The greater the number of vehicles on the road the greater the risk, and the less room for error.
The simple fact is that when ever there is a fatality on New Zealand roads, it will be because someone, somehow, somewhere, has made a mistake.
