A man suffered a more-than two-month delay in getting treatment after a doctor mistook testicular cancer for a cyst.
The doctor - who can not be named for legal reasons - was found in breach for failing to provide services with reasonable care and skill to a man with testicular cancer, Health and Disability Commissioner Anthony Hill found.
Hill instructed the GP to provide the man with a written apology as well as supplying HDC with evidence furthering his education and training regarding testicular masses.
The patient - who had a vasectomy noted in his medical records - presented to the doctor in April 2016 with a lump in his right testicle.
After examining the testicle, the doctor concluded the lump was an epdidymal cyst.
