A joint police and council initiative is aiming to reduce car break-ins at West Auckland beaches.
'Operation Speedo,' which is in its seventh year, begins today and runs until April.
It will see staff and volunteers from more than 14 organisations patrol West Coast beaches, dams and bush tracks.
Lifeguards, park rangers, parking wardens, visitor centre staff, firemen, Watercare engineers and postal staff will also be involved by reporting suspicious behaviour.
Waitakere Police Senior Sergeant Matt Srhoj said thefts from cars parked at Bethells and Piha beaches increased during summer.
