Containers full of premium NZ products have been flowing through the Port of Tauranga .. as it works to clear supply chain backlogs. On Monday a record 5326 containers including 1900 refrigerated were loaded on the Maersk Shams. Another ship due in port next month, will pick up a similar amount of containers. Kotahi chief executive David Ross says exporters are seeing constant schedule slippage, loss of capacity and shortages of containers. Maersk Oceania managing director Henrik Jensen says over the past eight months additional container shipping services have been introduced and increasing empty container positioning around the New Zealand coast. Meanwhile further south Napier Port expects shipping delays, storage issues and the shortage of containers to continue for the next 12 to 18 months. The company reported its half year profit has fallen 15 percent to $10.6 million.
