All but one of the people arrested in last year's anti-terrorism raids in New Zealand have been committed to stand trial.

Eighteen people have been facing 343 charges of illegally possessing firearms and explosives.

They were arrested during raids in October last year which focussed on Maori and environmental groups.

When the judge ruled there was not enough evidence to send one of the men to trial, supporters inside the Auckland District Court cheered and clapped.

Outside, protesters held up signs criticising police.

The other 17 people charged will stand trial and have been remanded on bail to appear back in court in February.
