Fewer WoF checks

Simon Bridges has announced:

Changes to New Zealand's warrant of fitness system, which will see annual inspections for cars registered after 2000, will save motorists time and money and will also focus on , says Associate Minister Simon Bridges.

The key changes to the warrant of fitness system (WoF) include:

  • An initial inspection for new cars, followed by annual inspections once  vehicles are three years old

  • Annual inspections for vehicles three years and older and first registered on or after 1 January 2000

  • Six-monthly inspections for vehicles first registered before 1 January 2000

Excellent. I find the six month WOF checks on relatively new cars a silly hassle and a of time and money.

The Motor Trade Assn will of course be unhappy, because they own a chain of testing stations. But mechanical defects are implicated in only 2.5% of vehicle crashes and are the sole cause in only 0.4% – experts have said the impact on safety will be minimal.

Ministry of Transport shows that the package of changes will benefit motorists and businesses by $159 million a year, and by at least $1.8 billion over 30 years.  This includes savings in inspection and compliance costs, and enforcement costs, and time spent by motorists getting their WoF.

Mr Bridges says these savings will have a flow-on benefit for the wider economy.

The MTA have also said there will be 2,000 lost due to this decision. Now of course that is a nonsense figure, but even if it was true their argument is flawed. The purpose of WOF checks is not to create jobs for garages, If that was the purpose, we'd have monthly WOF checks.

An economy does better when people get to voluntarily choose what they spend their money on. The annual saving of $160 million will benefit other areas of the economy.

The debate should be about balancing risk and cost.  I think this new regime is a far better balance than the old one.

The AA (which unlike the MTA has no commercial interests involved in the decision) has pointed out:

New Zealand has the most frequent vehicle safety inspection in the world. No other country requires cars aged 6 years or older (most of our fleet) to be tested twice a year.

Some countries have an annual inspection, and many only every two years. Others, like much of Australia and the , have no regular inspection at all.

Most vehicles in New Zealand are tested every 6000km. In Britain they're tested every 19,000km, and in Germany vehicles travel about 32,000km between inspections.

Yet despite these differences in inspection frequency the number of crashes caused by vehicle faults in New Zealand is about the same as other countries at about 2.5 per cent – or less than half a per cent where it is the sole cause.

This suggests that inspection frequency is not a silver bullet.

The question is, can we have a less-frequent test without increasing crash rates, and the evidence suggests we can.

This is a good example of the Government acting in the public interest, and refusing to bow to a scare campaign by vested interests. We need more decisions like this.
