From Morning Report, 7:50 am on 1 March 2017

Winston Peters says the reason young New Zealanders aren't getting jobs isn't because they fail drug tests, it's because National has opened the floodgates to immigrants who will work for low wages. "If anyone's drug addled here, it's the National Party who are addicted to immigration and can't give it up."
