New Zealand has posted its biggest monthly trade surplus in more than two and-a-half years because of record export values.
Official figures show a surplus of $640 million last month, the highest for a December on record, and the biggest surplus since March 2015.
Exports outpaced imports to $5.6 billion, because of record values for dairy products, such as milk powder, butter and cheese.
Stats NZ's international statistics manager Tehseen Islam said it was a solid result.
"The previous highest values for both dairy exports and total exports were recorded in the 2013/14 dairy export season, when dairy prices were at a high level," he said.
Imports fell from November to $4.9bn.
On an annual basis, the trade deficit narrowed to $2.8bn.
