The artist of a vandalised artwork on a Chorus cabinet in North Dunedin says the act is "really annoying".
An expletive-ridden video has surfaced of two men defacing the work, scribbling over the name of Dunedin band The Chills and writing the word "Coyote" underneath.
The pair appear to be members of Dunedin pop-punk band Coyote.
Artist Emma Craig said she discovered the video on Monday.
"Yeah, it's definitely really annoying. They're probably thinking it's a big joke."
Ms Craig reached out to the band who she said pretended they were not the culprits.
"They were being overly nice, and saying they will catch who did it, but you could tell it was fake. It's clearly the two people in the video."
She was now in the process of re-doing the work. "We're scraping it off and redoing the stencil."
The project was commissioned by Chorus.
In the video the disguised pair were being filmed by a third person.
The main offender calls himself "Banksy" and says they have "a message for the fat cats in the government..." before pointing at The Chills artwork, saying "this should say Coyote" and drawing over the artwork.
They then left "before the police come and arrest us...".
The incident appears to have happened over the weekend.
Senior Sergeant Ben Butterfield said police had not received any complaints about tagging but would investigate if a complaint was made.
