Total NZ Steel flat steel exports fell from 112,200 tonnes in the first half of the 2015/16 financial year to 48,100 tonnes in the latest period, while Pacific Steel long products fell from 42,000 tonnes to 6,200 tonnes on the same basis.
"Exports (are) reducing as Pacific Steel moves to billet supply from NZ Steel and (the) full economics of (the) Pacific Steel acquisition start to flow," slides accompanying the profit announcement say.
Ironsands exports rose in the first half, to 1.689 million tonnes from 1.395 million tonnes in the same half a year earlier.
Progress is being made with two potential buyers of the ironsands resource, the company said, although a maintenance outage on the buoy used by ironsands tankers for anchorage while loading the sands at sea will cost the company between A$10m and A$20m in second-half revenue.
The New Zealand segment is a relatively small part of the total Bluescope business, which has been pushing into North American and Asian markets in the last decade to reduce reliance on its Australasian base.
Total revenues for the group for the half year were A$5.2 billion, to produce ebitda of A$793m, compared with A$417.8m in the same half the previous year, reflecting a lift in global steel prices.
Net profit after tax for the group, including losses attributable to non-controlling interests, was some three times up on the previous half, from A$119m to A$360m and underlying earnings per share rose from 20.9 Australian cents to 62.8 Australian cents, prompting directors to lift the interim dividend from 3 Australian cents per share last year to 4 Australian cents per share.
