China is now New Zealand's largest trading partner, with two-way trade valued at more than $28b in 2018.
"Two-way goods trade with China is continuing to strengthen. On an annual basis, imports from China are twice the value they were in the October 2008 year, while exports have more than quadrupled," Islam said.
That relationship is coming under closer scrutiny as tensions between China and the US leave New Zealand stretched between an increasingly important trading partner and a traditional security ally respectively.
Trade Minister David Parker this month said New Zealand was trying to position itself as a link between world's two biggest economies which are locked in a trade war.
Meanwhile, Prime Minister Jacinda Ardern is coming under pressure to act as academic Anne-Marie Brady has faced multiple break-ins since writing a paper on China's use of soft power, and ministers are considering excluding Chinese technology firm Huawei from building 5G telecommunications networks.
Today's data showed exports were up 6.6 per cent to $4.9b, which Islam said were led by fruit and reflected "unusually high kiwifruit exports for an October month".
Kiwifruit exports are typically low in October, so both value and quantity in October 2018 were up sharply when compared with the same month last year. The total value of fruit rose $118m or 137 per cent to $204m, led by kiwifruit, which was up $112m.
Milk powder, butter, and cheese fell $43m or 3.3 per cent to $1.2b. Quantity fell 6.3 per cent. Milk powder led this fall, down $45m or 6.8 per cent. Quantity was down 12 per cent.
