Wellington City Council says a scheme to dob in taggers is working.
The programme has operated in Kilbirnie, Miramar, Island Bay and Khandallah, and is now moving into Tawa.
Those who tip-off community police officers to a tagger's identity are given $100.
CitiOperations manager, Mike Mendonca says more than 20 prolific taggers have been caught this year.
He says the cash payments have prevented damage which would have cost a lot of money to undo.
Local businesses are also being asked not to sell spray paint to young people.
