Limited services are now available for Roads and Maritime Services transactions affected by an overnight system outage.
Maritime licence and registration transactions can be carried out online, at registries and at Service NSW centres.
People who have motor vehicle licences or registration payments due today can visit a registry where a manual process will be carried out.
Driver tests previously booked can be taken and licences will be issued by mail.
Roads and Maritime will continue to work with service provider Fujitsu Australia to restore transactions as soon as possible and apologises for the inconvenience.
