More New Zealand transport companies have started billing a surcharge as a result of last month's earthquake.
Fastway Couriers is the latest to announce it has been forced to pass on some of its quake-related costs to its customers.
It said in a statement that it could no longer absorb the additional costs associated with diverting through Lewis Pass while large sections of State Highway 1 remain closed.
It will charge customers a 2.98 per cent surcharge from December 5.
"The decision to do so has not been made lightly and the surcharge will remain in place until SH1 re-opens and our linehaul network is permitted to use," the statement said.
