Signing the treaty

The 175th anniversary of the Treaty of Waitangi has got a bunch of contemporary Maori artists thinking about what those who signed the document would have been feeling when they put their name or mark on the document. The New Zealand Academy of Fine Art invited artists to put those thoughts on paper, canvas and into weavings and sculptures for an exhibition called Signing. Lynn Freeman talks to curator Ann Philbin and artists Gareth McGhie and Suzanne Tamaki.
