Kaikohe Community Watch founder Tony Taylor said the page, which turned a year old in July, had been such a success he sometimes had trouble finding crimes to keep it interesting.

Just yesterday he had been offered possible names for the "idiots" captured in CCTV footage of a break-in at the town's Countdown. After smashing in the front door, they took seven packets of mallowpuffs.
