Kiwis have joined in an online trend to broadcast a sound from a cult movie and TV series, heading onto the streets before last night's lockdown to play a "purge alarm".
The sound features in The Purge, a series of feature films and a TV series that tell the story of dystopian future where all crimes are allowed for a 12-hour period, which starts with the playing of the eerie sound.
The stunt has been pulled across the world, with people driving streets with speakers attached to their cars, with the alarm sound blaring.
The Herald has approached the police for comment on Kiwis' participation in the stunt.
A Facebook group in NZ was set up, titled Everyone Play The Purge Alarm At Midnight to urge Kiwis to play the sound.
