Fire crews attended more furniture fires in Castle St than any other Dunedin street from 2013 to 2016, an Official Information Act request to Fire and Emergency New Zealand revealed.
But last year, the hot spot lost its crown to Hyde St, which topped the list.
The number of furniture fire callouts in Dunedin has plummeted 86% in the past five years.
Incident numbers fell from 136 callouts in 2013 to 19 callouts in 2017.
Of the 19 callouts to furniture fires in the city last year, 79%, or 15, were in North Dunedin, six of them in Hyde St and four in Castle St.
Fire Emergency New Zealand fire risk management officer Mark Bredenbeck, of Dunedin, said furniture fires were a nuisance, a danger to the public and used resources.
"We are here putting fires out when we should be somewhere else,'' he said.
Crews in Dunedin had attended four "nuisance'' fires this year.
The four fires were in the north of Dunedin and the items burnt included a wheelie bin and a television.
The latest was a couch fire in Duke St, North Dunedin, on Sunday.
Mr Bredenbeck said nuisance fires in Dunedin were "diminishing''.
"People are starting to wake their ideas up - and I think that has a lot do with the university's stance.''
Fenz office of the chief executive director Leigh Deuchars said a joint initiative between Fenz, University of Otago's Campus Watch and Otago University Students' Association had been educating students on fire safety since the start of the 2017 academic year.
"The initiative involved a visit to every student flat and college dwelling was visited by Campus Watch who distributed information on fire safety and the issue of couch burning.''
The initiative, installation of CCTV cameras and the university's zero tolerance approach to arson had contributed to the decline in the number of couches being burnt, she said.
