Wellington's CentrePort said a strong lift in container traffic and property revaluations had driven its net profit $3.9 million higher to $17.9 million in the June year.
Port revenue was up 10 per cent to $73 million and the port's container trade was up 23 per cent to 132,000 TEU (twenty-foot equivalent units).
The log trade increased 19 per cent to 1.04 million JAS (Japanese Agricultural Standard).
The results include net fair value gains of $3.4m.
CentrePort said the result represented an 8.6 per cent return on equity.
