National's Justice Spokesman is standing by his suggestion of requiring gang members to cover up their gang tattoos with foundation. 

Mark Mitchell says National could potentially ban gang facial tattoos on top of patches, and gang members would have to apply make-up over tattoos, or face arrest. 

Labour's Megan Woods told Mike Hosking that it would be a hard rule to enforce. 

But Mitchell told Hosking that gang members have been charged and prosecuted for breaking a similar rule in Western Australia.
