Statistics New Zealand released its trade data on Monday. New Zealand's trade surplus narrowed to NZ$123 million in April from NZ$754 million in March. March's figure was revised up from a surplus of NZ$631 million.

The increase was driven by lower exports. Exports declined at an annual pace of 5.5% in April, while imports rose by 2.6%.

For the year ended April 2015, New Zealand's trade deficit was NZ$2.6 billion. It was the largest annual trade deficit since the year ended June 2009.

Statistics New Zealand said that it had received additional information too late. Additional information has not been included in April's release, and it may affect the petroleum and products import category, selected country totals and total imports for March 2015 and April 2015.
