A Kiwi who uses a silver fern symbol on his Twitter account
has been warned about copyright infringement by a government
The New Zealander said he chose the fern for his profile
picture and background because it was a "symbol of who I am".
But last week he received an email from New Zealand Trade and
Enterprise asking him to remove it.

Mr Swallow acknowledged that use by individuals was usually
