Television consumer affairs programme presenter Gordon Harcourt was left with a black eye, a bleeding nose and suspected concussion after he was attacked by a used-car dealer who had been the subject of a Fair Go investigation.



Harcourt was allegedly punched three times while filming in Mt Maunganui on Friday, the Herald on Sunday reported.



A 47-year-old company director has been charged with assault and will appear in the Tauranga District Court on August 4.



TVNZ's news and current affairs boss Anthony Flannery said Harcourt had been treated by a doctor following the attack and was told to avoid flying.



Police were still investigating the incident, head of Mt Maunganui CIB, Detective Sergeant Darryl Brazier said.
