In 1999, after helping establish a human rights presence in East Timor and Indonesia under Peace Brigades International, Alyn returned to New Zealand to take advantage of the peace and disarmament opportunities arising with the new Labour government under Prime Minister Helen Clark. Although based in New Zealand, this work required extensive travel, particularly to North America, Europe and Asia. This included ongoing work at the United Nations including the drafting and presentation to the UN Security Council of a Judges and Lawyers' Appeal on the Illegality of the Preventive use of Force - one of the initiatives which helped ensure that the UN Security Council did not authorize the US-led invasion of Iraq in 2003.
Alyn currently holds the positions of:
- Director of the Wellington office of the Peace Foundation, a peace education activity in New Zealand schools and communities;
- Vice-President of the International Peace Bureau, in which he is most active on their Disarmament for Development Program;
- Consultant to the Lawyers' Committee on Nuclear Policy and the International Association of Lawyers Against Nuclear Arms (IALANA) for which he is responsible for the programmes promoting Nuclear Weapon Free Zones and a Nuclear Weapons Convention;
- New Zealand Coordinator of the World March for Peace and Nonviolence which started in New Zealand on 2 October 2009 and is travelling around the world promoting nuclear abolition, an end to war and the prevention of violence at all levels of society;
- Co-Founder and International Coordinator of Parliamentarians for Nuclear Non-proliferation and Disarmament (PNND), which engages legislators from across the political spectrum in nuclear disarmament issues and initiatives; and
- Board member or advisor of a number of other international organisations including Abolition 2000, Middle Powers Initiative, Peace Boat, Mayors for Peace and the Global Campaign for Peace Education.
