Members of a group who believe they are exempt from NZ law used fake ID to reach the PM's floor, according to a police presentation.

The police powerpoint presentation, released to Stuff under the Official Information Act, said members of sovereign citizens group Mauri Nation used fake ID to reach the Prime Minister’s floor at Parliament.

The presentation from the Police Security Intelligence and Threats Group in November last year, does not say whether the Prime Minister - then Jacinda Ardern - was present.
