A judge presiding over an application for a judicial review of new rules restricting the import of cars ahead of emission standards has reserved his decision.
The application was made by the Imported Motor Vehicle Industry Association and relates to the emissions standards law introduced in 2008.
The association claims a promise was made by former Associate Transport Minister Judith Tizard to review the effect of the law within three years of it coming into force.
From January next year, new emissions standards will affect the importation of Japanese cars made prior to 2005.
The association argues this will restrict the quantity of cars coming onto the market and push up prices for consumers.
It also argues people will hold onto older cars for longer, which will have a detrimental effect on air quality.
