A masked duo who terrorised people in and around Auckland Domain may have been engaged in what public relations specialists have called a "misguided" publicity stunt.

The man and woman who dubbed themselves Twins of Atticus have been spoken to by police after reports of their frightening behaviour in Parnell and the Domain over the past few weeks.

Student film-makers caught the pair on film, emerging from bushes with white masks and brandishing fake guns.

The pair responsible came forward after police publicly warned them to "wise up", warning them that they were putting themselves in danger as reports of people wielding guns would always be followed up by armed officers.

"Drop the masked act and come and talk to us about how to play safely," police spokeswoman Noreen Hegarty said on a police Facebook post.

Today she said the pair hadn't been arrested but that "they are in no doubt about what we expect of them".

Yesterday the duo appear to have created a Facebook fan page for themselves in the name Twins of Atticus, but haven't responded to messages from Stuff.

The page boasts pictures of a gun-toting woman and links to an adult-themed blog.

However their new-found celebrity has been met with derision, with many people posting messages of scorn on their page.

"Shame on you for scaring the s*** out of people," wrote one critic.

"Wielding guns(albeit fake) and intimidating people in public parks, including children with their parents. A misguided attempt at a political statement perhaps? or just bored and aimless?" another said.

Movie industry insiders said they believed it was a publicity stunt, but if that was the case Trigger marketing and publicity managing director Adria Buckton said the stunt had failed at the first hurdle.

If people came away feeling fearful or afraid, then the stunt was a no-no, she said.

"If (the stunt) involves fire arms it's not something we'd get involved in. I imagine they wanted mass media coverage but in terms of value to their brand, I personally wouldn't think the outcome has been great.

"It was a misguided strategy if that's what was intended."

She said people were more fearful than usual and had heightened awareness when it came to guns as a result of the Sydney attacks, and a shoot-out at an American cinema showing of Batman in Colorado that left 12 dead.
