The improvement in underlying earnings is largely due to expansion of Northport Ltd export log trade, which increased by 24 per cent to 2.4 million tonnes in 2012/13.
Log volumes increased over the second half of last year, when cargo throughput reached 1.659 million tonnes, up 7.6 per cent on the same period in the previous financial year.
Indications suggest export log volumes through Northport will continue at existing levels for the foreseeable future while annual cargo throughput for all trades is expected to exceed 3.2 million tonnes in the current financial year (2012/13: 3.095 million tonnes). Group earnings for the year are expected to rise if these tonnages are reached.
Sir John said initiatives over the past 18 months to increase storage capacity in the port terminal were already producing operational efficiencies. Growth in cargo volumes was likely to ultimately require construction of a fourth berth, for which initial designs were now being reviewed.
A fully imputed interim dividend of 5c a share (2012/13: 4.5c/share) will be paid out on March 21.
