"We are aware of nearly 300 thefts that took place in the first three months of this year in which we believe replacement keys using illegally obtained key codes were used to steal the vehicle," said NICB CEO Joe Wehrle.
"We are working closely with our member companies, law enforcement and the vehicle manufacturers to track these illegal key code transactions and stop the thefts or recover the stolen vehicles before they can be resold here or shipped out of the country to be sold overseas."
Though late-model sports and luxury cars tend to be swiped intact and sold with swapped identification numbers and laundered documents or sent to other countries, more-common models like these - especially older examples that lack the aforementioned key-code anti-theft technology - are usually driven or towed away and immediately dismantled at so-called "chop shops".
While the recoverable value of any of these dated models tends to be comparatively minimal, they're worth far more as an amalgam of salvaged used parts sold by unscrupulous vendors.
In New Zealand, it seemed Nissan was the car favoured by car thieves. The Aucklander studied the number of cars stolen in Auckland City, Waitemata and Counties-Manakau in the six months to the end of August and Nissan comes out on top as car of choice for thieves.
Of the 1111 cars police records show were stolen across Auckland in that time, 214 were Nissans, with the Terrano stationwagon being the most popular model stolen (30).
In the sedans, the Primera was the most popular model (21) followed by Skylines (19) and Pulsars (16).
Next targeted were Toyotas (160), Hondas (93), Mitsubishis (88) and Mazdas (74).
