New Zealand is the world's largest exporter of dairy products and has benefited from an increase in global dairy prices over the past year. Dairy products led the country's export gains last year, with the value of milk powder, butter and cheese jumping 25 per cent to $14b.
Exports of meat and edible offal, the country's second-largest commodity export, rose 12 per cent to $6.6b. Meanwhile exports of logs, wood and wood articles, the third-largest group, advanced 13 per cent to $4.7b, Stats NZ said.
On the other side of the ledger, imports of mechanical machinery and equipment such as aircraft parts and computers jumped 19 per cent to $8.2b, while imports of vehicles, parts and accessories, which is a category mostly made up of cars, trucks and vans, rose 16 per cent to $8.9b.
For the month of December, record exports of dairy products drove total exports to their highest ever monthly value, Stats NZ said. Total exports surged 26 per cent to $5.6b, led by a 30 per cent gain in dairy exports to $1.9b. Imports for the month increased 11 per cent to $4.9b, led by a 21 per cent gain in the value of mechanical machinery and equipment such as aircraft parts to $807 million.
The monthly trade balance for December turned to a surplus of $640m from a $1m deficit in the same month a year earlier. The surplus is the largest for any December month, and the largest in any month since March 2015 which recorded a $661m surplus.
