A children's playground is one alternative to the $35,000 spent on vandalised road signs in Whangārei this year.
A Give Way sign changed to "Give Head" on Winger Crescent in Kamo was the latest costly joke added to the lengthy bill footed by ratepayers for graffiti repairs, with many containing the same wording.
Mike Batchelor, Northland Transportation Alliance maintenance lead, said contractors had fixed 532 incidents of defaced road signs since January.
"Usually we don't have to replace the entire sign - just clean it up - and that costs about $98 per sign when you take into account time, mileage, clean up and replacement."
A consequence of road sign pranksters that bares an even higher price tag is the risk to motorists, the boss of Northland road policing, Senior Sergeant Steve Dickson said.
