Protesters are forming a human blockade at a defence industry conference in central Auckland today.
The annual New Zealand Defence Industry Association Forum is being held at the ANZ Viaduct Events Centre.
The world's largest nuclear arms manufacturer, Lockheed Martin, is the main sponsor of the forum, which will be attended by arms dealers from all over the world.
Protest organisers Auckland Peace Action organised the blockade to stop the opening of the forum at 8am. More than 500 people have said they will join the protest.
Protesters will be addressed by former Auckland mayoral candidate Chloe Swarbrick, Nobel Peace Prize nominee Dr Helen Caldicott, Auckland councillor Cathy Casey and Patrick Hinchcliff, the grandson of the AUT University founder.
