The container ship had its own cranes, but had been worked by onshore cranes operated by local stevedores.
“Initial reports from local workers suggest an incident had occurred when onboard cranes were being moved by crew,” Harrison said.
The MSC Resilient III is a Liberian flagged container ship which left Melbourne on December 15, according to online shipping logs.
The Maritime Union had concerns about the health and safety aboard overseas flagged ships working in New Zealand ports.
“The Resilient III is a flag of convenience (FOC) vessel registered under the Liberian flag. FOC vessels are notorious for the issues around safety and seafarers’ rights.”
Maritime New Zealand spokesman Adam Walker confirmed it was investigating.
