The latest Export New Zealand DHL Export Barometer shows about four in five have maintained or increased export volumes over the past year.

While US-bound goods are now being hit with higher tariffs, businesses are diversifying more into other markets like the UK and Japan.

Three in five exporters expect further growth in the coming year.
