The ACC levy on motor spirits will be 6 cents per litre from 1 July 2017. The levy does not apply to diesel.
The levy is set in the Accident Compensation (Motor Vehicle Account Levy) Regulations 2017, and Customs collects the levy for ACC.
The ACC levy on motor spirits helps to pay the costs of motor vehicle injuries on public roads. The levy only partly meets the costs of motor vehicle accidents, the rest is paid through the vehicle licensing fee (rego). A person who is injured in a motor vehicle accident can claim entitlements such as medical treatment, weekly compensation if they are unable to work, and other assistance such as home help and childcare.
