Port Otago has generated $7.3m for parent organisation the Otago Regional Council in the last financial year.
The company's just publicly announced its latest annual performance, reporting a group profit of just over $34m.
There has been an increase in export container volumes and higher valuations on investment properties.
But the log industry has declined slightly, as have import container volumes and cruise ship numbers.
Port Otago's well into its planned $45m infrastructure upgrade, spanning several years.
