MPs are urging that a bill banning gang patches from government and public buildings be widened to ensure that it is clear police and school premises are included.
The bill, in the name of National MP Todd McClay, would give police the power to arrest anyone they believe had broken the law and could result in a $2000 fine.
Parliament's law and order select committee says police and school buildings are currently not legally defined as public service premises and should be included in the gang patch bill.
MPs have also recommended changes to stop gangs dodging the ban by changing their name slightly from the one listed in the legislation.
