The annual meeting of the international Nuclear Suppliers Group, which aims to stop the spread of nuclear weapons, is under way in Christchurch - the first time the group has held a meeting in New Zealand.
It's expected China will make a formal statement at the gathering about its proposed sale of two nuclear power-generating reactors to Pakistan.
New Zealand is one of 46 countries which formed the group in 1974 to regulate the trade in nuclear materials.
Disarmament Minister Georgina Te Heu Heu says although New Zealand doesn't trade in nuclear items, it does trade in some hi-tech goods which are deemed sensitive.
The group's guidelines cover dual-use goods, which are those designed for civilian use but could be used in weapons.
