Tough anti-bikie legislation has been passed in the Northern Territory even though similar moves have been shot down in another state.

The NT government is adamant it won't suffer the same fate as its South Australian colleagues, who have been forced to take their bid to curb organised crime to the High Court.

The move followed a state court ruling which found parts of its controversial anti-bikie laws invalid.

Under the laws, the attorney-general has the power to declare any group - not just a motorcycle club - a criminal organisation.

Police could then ask magistrates to place control orders on a group's members, effectively banning them from associating with each other.

Similar legislation was passed by NT parliament on Wednesday night as part of a national push to dismantle outlaw motorcycle clubs.

But NT Attorney-General Delia Lawrie said Labor had been advised the step was legal.

"I have received advice from the solicitor general that the recent decision by the South Australian full court invalidating part of the South Australian legislation would not apply to our legislation," she said.

Ms Lawrie said the NT laws included "checks and balances" on the new powers and responsibilities granted to police, the courts and judicial officers.

"It needs to be stressed the new laws do not diminish the freedom of Territorians to take part in advocacy, protest or industrial action," she said in a statement.

Once an organisation is declared under the new laws and control orders are put in place, it will be an offence for members of that organisation to associate with each other.

It's hoped the move will prevent the NT from experiencing the gang-related violence seen in southern states.

"The passing of these laws is part of a national approach to stamp out the criminal activities of organised crime syndicates and illegal bikie gangs," Ms Lawrie said.

"These new laws will restrict and disrupt activities of people and organisations involved in serious criminal activity."

NSW maintains its anti-bikie laws are different to SA, and both Queensland and Western Australia have vowed to press ahead with their own legislation.
