Prime Minister John Key defended New Zealand's "100 per cent pure New Zealand" tourism campaign in a speech to a tourism conference in Bali focusing on sustainable development.
Mr Key who is Tourism Minister as well as Prime Minister is in Bali for the Apec leaders' summit.
He said the 100 per cent pure campaign had been hugely successful since it was first used to market New Zealand internationally in 1999.
But he warned that it was not an environmental statement.
"I think it is important to be aware that 100 per cent Pure New Zealand is not an environmental message - and couldn't be anywhere in the world."
