A social media story claiming Auckland residents are at risk of being robbed by gun-toting plumbers is a leaky, entirely made-up hoax, police say.
The message, which has circulated online and by text messages, warns people to be on the lookout for burglars impersonating water servicemen in order to gain entry to your home.
The men offer to install energy saving shower heads or change lightbulbs, then rob you at gunpoint, the chain-mail type message says.
A number of Auckland residents have reported the message to police but a statement released by police this afternoon said it had "no basis in truth".
They have urged any residents fearing an armed break-in to ease their guard, and not pass the message on.
"It is completely untrue and the text should be ignored," a statement said.
The message is believed to have been circulating since 2012.
As with many hoax crime alerts, it originated overseas and has spread via the internet.
