MAERSK announced changes to its trans-Tasman Polaris service, affecting ports in both Australia and New Zealand.

In an advisory, Maersk said the changes were following the “prolonged disruption at Australian ports due to the ongoing industrial action”.

Maersk said the changes would “improve frequency between Australia and Port of Auckland, while strengthening the resilience of our overall Oceania network”.

The Polaris service will call Auckland weekly and the current port call at Melbourne will be replaced with a weekly call at Patrick’s Port Botany terminal.

The service will continue on a weekly basis, still calling at the New Zealand ports of Nelson, Timaru and Port Chalmers.

The new rotation of the Polaris service will commence on 13 December with the 2240-TEU Nicolai Maersk calling Sydney.

The new Polaris rotation will be: Sydney – Auckland – Nelson – Timaru – Port Chalmers – Sydney

Maersk’s announcement comes days after ANL announced changes to its trans-Tasman Tranztas service.
