If you've ever wondered what happens to guns seized as exhibits of crime or surrendered to police, look no further.
Counties Manukau Police have posted a video to their Facebook page showing Sergeant Chris McDowell explaining the process.
The firearms, which have either been seized from criminals or surrendered from deceased estates, are collected and taken to a scrap car crushing yard.
There the weapons, some still in their cases, are loaded into a car and on to a large conveyor belt to be crushed.
The guns of all shapes and sizes are destroyed by the car crushing yard and come out on to a heap as small bits of scrap metal.
