The ship can carry 4578 TEU (standard sized containers).
This is considerably more than the 4100 TEU capacity of previous large ships to New Zealand. These were operated by Maersk, although the largest capacity ship to ever visit the country was the Maersk Detroit last year - a ship with a capacity of over 5000 TEU.
