China is New Zealand's largest source of imports at $17.2bn in 2023, representing 16% of our total global imports. Over the last decade, imports from China have grown an average of 4.7% per annum in real terms. This trade relationship benefits Kiwi households and firms through China's comparative advantage in manufacturing, particularly consumer and household goods.
China has emerged as the world's factory, with its share of global manufacturing value add rising to 28.9%, with the US in a distant second at 16.1%. This reflects a realignment from old manufacturing powerhouses – the US, Japan, and Germany – as lowered trade barriers and better transport links have enabled countries to focus on their comparative advantages.
Our import trade with China is dominated by goods, particularly consumer goods. Of our top 15 non-petroleum product imports totaling $14.9bn in 2023, $5.6bn (37.4%) was sourced from China, with shares as high as 80% for some products.

Our import relationship with China extends beyond direct imports. When we look through the entire supply chain, China's contribution to our economic output amounts to 20.5% of the portion sourced from overseas. This is the largest of any of our trade partners, but we must keep in mind only 18.9% of our output is sourced from overseas.
Compared to other countries like Singapore (44% foreign inputs), New Zealand isn't particularly exposed to foreign inputs. Even when importing from other countries, we are still indirectly linked with China through global value chains. Diversifying away from China for non-market reasons is likely to be costly and challenging, as many alternative markets will themselves be integrated with China.
