Wilson Parking, which does not operate the Wellington Airport car park, has an established protocol in relation to abandoned vehicles.
A Wilson Parking spokeswoman said once a vehicle was identified as potentially being abandoned, it was monitored for a further week by the site manager.
If it was confirmed stolen, it was relocated to police recovery.
If it was not stolen and the owner couldn't be contacted, the car would be stored and eventually deregistered and sold to cover costs.
The red Honda Accord was wanted by police after a group of South American thieves robbed foreign jewellery dealers in Auckland in 2011.
The group travelled to New Zealand on false passports, bought cellphones and hired rental cars.
They robbed $110,000 from their first victim, an Australian named John Wertheim, and two weeks later struck two Hong Kong buyers, Chin Fung Ng and Aska Lo, outside the Rydges Hotel in Federal St, robbing them of $610,000 of jewellery.
