Auckland's port company has come back strongly after navigating some choppy financial waters.

It's confirmed this year's net profit after tax increased by more than $50 million, following last years $10 million loss.

The dividend to its parent Auckland Council have also increased by $15.8 million, to $30 million.

Ports of Auckland CEO Roger Gray told Mike Hosking their continued success is dependant on a strong economy, but things are looking promising.

Gray says the long term goal is to get to $80 to $100 million year net profit after tax.
