If you want to keep your town pristine and graffiti-free, Brian McWilliams might have some ideas for you.
As community facilities manager at Carterton District Council, it is Mr McWilliam's job to look after the appearance of the town.
He said the best measure a town can take against taggers is to ensure public spaces are open and well-lit.
This includes cropping low branches and having lights positioned low to the ground.
Public toilet walls have a "Uracryl" layer painted on them so tags are easy to clean off.
