I went through some of the definitions in the legislation, because I was kind of looking at it and it said "UPOV convention" and I wasn't sure what that meant. So, the International Convention for the Protection of New Varieties of Plants was signed in 1961, revised in '72, '78, and '91. Our piece of legislation that we're bringing through tonight is adding a modern focus, which also includes the Treaty of Waitangi in that aspect. So it is simply, clearly something that has been left alone for a long time and needs to be modernised.
