Improved sales of dairy products and oil helped New Zealand to post its second consecutive annual trade surplus.
Figures from figures Statistics New Zealand show the trade balance for the 12 months to the end of May was a surplus of $91 million.
It follows a surplus of $182 million for the 12 months to April.
New Zealand exported $4.2 billion of goods in May - 6% more than the same month last year.
ASB economist Jane Turner says exports benefitted from seasonal strength in agricultural production, particularly dairy and meat products.
New Zealand imported $3.4 billion of goods in May, up almost 3% on April, and 11% more than the same month a year ago, because of more imports of petroleum products, vehicles and parts.
