The value of exported goods has fallen for the first time in almost a year.

Last month's value was down 3.3% to $3.7b, compared to July last year.

That shows a decrease of $125m.

Exports decreased over a range of commodities, but the fall was led by pine logs.

Over the last 10 months, milk powder, butter and cheese values have risen.

Seasonally adjusted exports fell 7.5% last month, and imports 1.8%.
