Real-life Grinches have tried to steal Christmas by wrecking Kerikeri's Christmas tree and making off with the lights.
The tree, which is located outside the surf shop on the town's main shopping street, was vandalised between 2.15am and 3.15am on Monday.
CCTV footage shows three youths initially attempting to remove the lights.
When they became frustrated after about an hour they instead started destroying the lights and prising open the tree's base to steal the programmable light controllers.
