New Zealand wants to improve the overall fuel economy
of the nation's vehicles, and scrapping older vehicles is part of the plan. Automakers say lawmakers need to take action rather than continuing to review and discuss more options. Besides restricting the age of imported used vehicles, officials are considering a sales-weighted fuel-economy standard. Trying to adapt fuel-economy standards to the used-vehicle industry might be difficult, so a rolling 7-year age limit to all imported vehicles is favored by many. Critics say more efforts are also needed to increase the scrappage rate of older vehicles, possibly by offering incentives. Officials are also struggling with an exemption for large trucks.
