An unexpected trade surplus last month shrank the annual deficit to its smallest since last September, but economists expect the drought to widen it again.
Exports exceeded imports by $414 million or 12 per cent in February, defying market forecasts of a small deficit.
At $3.9 billion, exports were 8 per cent higher than in February last year, underpinned by a 24 per cent rise in dairy exports and a 12 per cent rise in logs. The exchange rate appreciated 4 per cent over the year.
Imports at $3.5 billion were up a more modest 2.5 per cent from a year ago, with consumer goods, cars and oil all higher but imports of capital plant and machinery 5 per cent lower.
The annual deficit was $1.1 billion, the smallest since $900 million in the year to September 2012, as exports fell 4 per cent from the year before while imports were flat.
