The spate of tags started appearing late in 2009, but while Mr Forster said it appeared to have stopped about the end of last year, it was not over until police searched an address in Hastings on April 18.
Kitchen admitted he had been tagging for four or five years, and said that rather than intending to cause any damage he had done it "for the art".
It had become like an "addiction," he said.
The four charges represented four groups of victims - network services specialists Chorus which had facilities and fixtures tagged more than 200 times, the Hastings District Council with more than 100 attacks on its property, the victims of 115 tags on commercial premises, and 25 residential victims.
Judge Mackintosh said Kitchen "forged" on in the face of warnings from the courts of a toughening stance, and of the ire of a community which believed graffiti was an expensive and distressing nuisance.
The district council, she said, was not on the same "wave-length" as Kitchen in his view that it was "art," and a commercial victim had counted the hidden costs in emotional stresses and effects on staff morale.
A probation report on Kitchen showed he initially thought it was good to see his tagging "out there" in public, but since his arrest he had shown insight and was "now more annoyed" with himself.
Mr Forster said yesterday Kitchen had been in work about five months, the end of his graffiti appearing to have come about the time he obtained employment. He said an order of reparation for $15,000 could realistically be paid off by Kitchen.
As well as admitting the damage charges, Kitchen admitted possessing 19g of cannabis which was found in the search of his home.
