Rental cars will be fitted with technology that will enable safety messages to be beamed directly to their drivers in a new trial launched today.
The initiative will see messages sent from roadside transmitters along the key route between Christchurch and Queenstown.
The safety messages will initially be in English, but NZTA would look at adding other languages if the trial was successful.
It comes after a spate of devastating crashes involving tourist drivers on New Zealand's roads and calls for more to be done.
Up to 50 GO Rentals vehicles will be fitted with the devices, which will transmit up to 70 audio messages ranging from reminders about road conditions and road rules, to suggestions about good places to break the journey and travel times.
