There are growing concerns about a niche subculture of “sirening”, which has led to a rise in tsunami siren thefts across Auckland.
In the past year, 52 tsunami sirens have been stolen across Auckland, an increase of 21 since the last update in October last year.
During the last update, an Auckland Emergency Management (AEM) spokesperson said it was suspected the units were used for “siren battles” or “sirening”.
The sirening subculture involves attaching the stolen sirens to the front of a car or bike and playing music through them.
Sireners, who are usually part of “crews”, play a mix of music with high treble suitable for the siren speakers and battle across Auckland most Saturdays, with crews vying to see whose sirens are loudest and clearest.
