The country has two ports of entry, the main port, Port of Avatiu on Rarotonga and Port of Arutanga, which serves the island of Aitutaki. 

Port of Avatiu is capable of accommodating container and fuel tanker vessels up to 200 m in length and is responsible for handling almost all the country’s export and import cargo. A small percentage is taken directly to Aitutaki to service the needs of the locals and tourist resorts there, however large vessels cannot berth and cargo must be transhipped to shore by barge.

All the Outer Island harbours are small and shallow; freight shipped to these islands must be transferred to barges or other small vessels to be landed.
