The Trade Minister says he'll be making the case against further US tariffs on New Zealand lamb. 

Todd McClay says he expects the US Government to launch an investigation into our lamb exports in the coming weeks. 

It could result in extra tariffs being imposed to protect the US sheep meat sector. 

McClay told Mike Hosking he and his officials will be reminding their US counterparts of the mutual benefits of the trade. 

He says lamb consumption and lamb prices in the US have gone up as a result of New Zealand's marketing efforts.
