Prime Minister John Key says major companies such as Fonterra have been asked not to exploit the gap left by other countries' trade sanctions on Russia because to do so would be a "terrible look" for New Zealand.
Before leaving the G20 summit in Brisbane yesterday, Mr Key also joined his voice to those of other leaders to confront Russia's President, Vladimir Putin, over Ukraine and the downing of the Malaysia Airlines flight.
Mr Key said he had spoken to Mr Putin during the summit's leaders' dinner when he was seated two down from the Russian leader. He said the conversation was largely an exchange of pleasantries but he reminded Mr Putin two New Zealanders were killed on MH17.
