The New Dunedin Hospital logo is so similar to one used for a sex education programme that at least one of them will probably have to change.
One agency designed them both, the Ministry of Health said, and taxpayers should not need to fund any fix.
The Southern District Health Board sought a logo for the hospital project in early 2018. The logo, with minor changes, has been used in all internal and external communications on the high-profile construction project since.
A similar logo has been used for years by the Theatre in Health Education Trust, for Sexwise, a sexual health programme for secondary school students.
