The Lyttelton Port company has reported record trade volumes in the 2011-12 year, lifting revenues by 40% on the previous year.
The company posted an after-tax profit of $17 million, an increase of 40% on last year's $12 million profit.
Port chairperson Rodger Fisher says the results reflect the record number of containers and coal volumes moving through the port and was achieved despite on-going earthquake repairs.
Mr Fisher says imports are expected to continue to grow as the rebuild of Christchurch gathers pace.
