"However, the fall follows a large run-up in dairy export volumes. Between March and June volumes had increased by 33 per cent, so in this context, a pullback is no surprise," Penny said. "This also points to the earlier run-up being driven by a rundown in stocks. Indeed, as dairy production picks up over the new season, dairy export volumes will recover."
Overall, exports rose 9 per cent to $3.69b in August compared with the same month a year earlier, lagging behind expectations for the month of $4.05b. The value of fruit exports jumped 29 per cent to $311m and kiwifruit was the leading contributor to the gain, with exports up 37 per cent to $268m. Exports of gold kiwifruit increased 55 per cent to $45m, while the quantity rose 26 per cent. Green kiwifruit exports increased 25 per cent to $28m, while the quantity rose 17 per cent.
Other exports which gained in the month were petroleum and products include crude oil, which increased $54m, food preparations including infant formula, up $44m, and mechanical machinery and equipment, up $27m.
Meanwhile, goods imports rose 6.5 per cent, or $301m, to $4.92b in August, ahead of expectations for the month of $4.8b. The increase was led by a 93 per cent jump in the value of crude oil, which added $147m to imports.
The statistics agency noted that imports of crude oil and other petroleum products tend to move up and down from month to month, depending on the timing of shipments.
The annual deficit in the year to August was $3.2b, little changed from $3.12b a year earlier. Economists surveyed by Bloomberg had expected an annual deficit of $2.91b.
"Monthly volatility aside, we expect the annual trade balance to narrow over the remainder of the year mainly on the back of firm agricultural export values," said the ASB's Penny.
