The Trade Minister's been seeking more information about the numbers the US is using to justify new tariffs

Donald Trump's rolled out tariffs of at least 10-percent on almost all goods.

His administration claims New Zealand imposes a 20-percent tariff on US goods, when our average tariff on US goods is actually less than two-percent.

Todd McClay says he's received a report on the discrepancy overnight.

He says they appear to have factored in the difference in the value of trade last year, which is quite different from a tariff rate.
