The new government is vowing to take a hard line with gang members, including those with tattoos showing gang affiliations.

The political parties that will soon form the new government all promised a crackdown on gangs. The banning of gang patches will be their first move and a ban on visible tattoos could follow.

Helena Carter has been removing Auckland-based prisoners' gang tattoos for around a decade.

Gang members covering their facial tattoos with make-up sounds laughable but hardcore bikies might find it preferable to the alternative.

Having your tattoo removed is like getting hot fat poured on your skin, says Helena Carter, owner of deINK Tattoo Removal.

But that doesn't stop the months-long queues of prisoners wanting the markings off their faces and necks.

About a third of Carter's work is in Auckland prisons with her laser machine, soothing her clients as she puts them through the excruciating pain of getting rid of their tattoos.

Large tattoos take several sessions and the longer the session the more painful the removal, but Carter says it is not safe to do it all at once.

"The ink is being released into the body and it can overwhelm the body. When we hit it with the laser it explodes the ink into much smaller molecules and then the body comes along and eats up the molecules," Carter tells The Detail.

A healthy body will take three months to get the ink out of the organs.

Carter says even the most hardened prisoners are nervous about the procedure and she uses humour to ease them.

"When they first come I go, 'ooh you haven't been tortured by me before, have you?'"

Her work is mostly funded through a programme for tattooed prisoners who would struggle to get on with their lives once they are released if they didn't have their markings taken off.

Taxpayer-funded prisoner tattoo removal is controversial but Carter says it is important to support them.

"Not all people got their tattoos willingly. All we can do is help when they're ready to get out the other side, and if we don't, then those guys don't stand a chance."

The new government is vowing to take a hard line with gang members, including those with tattoos showing gang affiliations.

National MP Mark Mitchell told RNZ's Checkpoint that gang members may be made to wear makeup to cover tattoos.

The man expected to be the next police minister, Mark Mitchell, says the police will be allowed to search suspected gang members, their vehicles and properties without warrants, and issue dispersal notices banning gang members from talking to others. Gang activity would also be banned on social media…
