Global shipping line Maersk yesterday announced a penalty charge for freight crossing Auckland's wharves, as more than 300 port workers began a three-week strike.
The company told customers it could no longer afford to carry "significant extra costs" caused by the industrial turmoil, which in December it blamed in part for a decision to move about 40 per cent of its Auckland business to Tauranga.
What it is calling its "Auckland strike surcharge", to be lifted only if and when stability can be restored to the port, would amount to an extra US$80 ($95.60) for each 20-foot (6.1-metre) container, and double that for 40-foot (12.2m) boxes.
Importers Institute secretary Daniel Silva estimated that would increase freight charges from China by about 6 per cent and be passed on to consumers.
Maersk, which is the world's largest shipping line, said the levy would apply to all export and import cargoes.
