The Trade Minister's hitting the phones, as it's confirmed US tariffs on New Zealand will be higher than when they were first announced.

The Trump administration has confirmed base tariffs will now be 15 percent -- up from 10, in a decision that impacts countries including New Zealand.

It's believed the new rate applies to those with a trade deficit with the US.

Todd McClay told Heather du Plessis-Allan that he's seeking an urgent call with American representatives on this.

He says it's disappointing and challenging for exporters, and while there are opportunities, tariffs aren't good for trade.
