Across the country there were 4.7 million vehicles in 2023, up from 2.9 million in 2004. This was an increase of 52%, but the population only grew by 28% in the same period.
Southland had the highest rate of car ownership in the country, with a whopping 987 vehicles per 1000 people, closely followed by the Nelson-Tasman-Marlborough region on 972.
By comparison, Wellington had the lowest rate of car ownership with just 696 vehicles per 1000 residents.
