A number of organisations opposed to nuclear weapons and nuclear power emerged in the 1970s and 1980s, ranging from international organisations like Greenpeace and CND (Campaign for Nuclear Disarmament) to those that were specific to New Zealand.
A feature of these organisations was the development of posters, badges and similar material that promoted the anti-nuclear cause. An example of the sort of badges developed by these organisations can be found at the start of the feature Nuclear-free New Zealand. Using these and any other examples of material promoting an anti-nuclear stand that you can find, design either an anti-nuclear badge, similar to those shown, or an A4-size flyer that promotes the idea of a nuclear-free New Zealand.
