The Trade Minister's cautiously welcoming a rollback of US tariffs on food imports including New Zealand beef, offal and kiwifruit.

US President Donald Trump's signed an executive order reducing the tariffs.

The affected New Zealand products represent around 25 per cent of our exports to the United States, worth more than two billion dollars annually.

Trade Minister Todd McClay told Mike Hosking that it's still a very uncertain time for Kiwi exporters.

He says he's concerned about the changing nature in the White House and even though it's been reduced, the tariffs could be brought back.
