Police are introducing a new type of road spikes designed to save lives during police pursuits.
Calls came to replace the existing road spikes after 14-year-old Rotorua boy Pehi Tahana died in February.
He lost control of a stolen car after driving over police road spikes during a chase and crashed into an oncoming van.
Police revealed in the latest Police News magazine that a bulk order of US-made Stinger road spikes had been made and would be deployed nationally by March next year.
Coated in plastic, the Stinger spikes can penetrate all tyre types and are designed to prevent blowouts by allowing for the slow release of air - allowing drivers to come to a safe and controlled stop.
