Dozens of police attended Paremoremo prison this morning because they were expecting a "gathering" outside the prison - but it never happened.
A witness who asked not to be named said about twelve police cars were at the maximum security Auckland Prison, covering every entrance.
At nearby Sanders Reserve about 14 police were visible, and a police transporter, a prison van and three police cars were parked up, he said.
Police had been at the prison on the North Shore since at least 8am.
