When Harcourt returned last week, he was left with a black eye, bleeding nose and suspected concussion after being allegedly punched three times while filming on the pavement outside the car dealership.
TVNZ will broadcast an investigation into a Mt Maunganui car dealer tonight. Excerpts of the incident have been shown on adverts and posted on its website last night.
The excerpt shows Harcourt with blood running from his nose to his teeth telling the camera: "Well, just came to do some filming and as you can see, things got a bit nasty."
Harcourt is shown speaking to the camera when a man suddenly appears and a scuffle breaks out amid expletives, with Harcourt yelling: "Hey mate it's not your property, it is public property ... and that's not yours, pal."
A bloodied Harcourt is shown talking on his cellphone explaining his crew "just got our equipment out of the vehicle" as it wanted to film on public property outside the premises.
The programme has received criticism and support with one person posting: "If you go around doing this, without appropriate security measures in place, then you're asking for it and you'll get it eventually."
A 47-year-old company director has been charged with assault and intentional damage after a camera was damaged during the alleged scuffle and is due to appear in the Tauranga District Court tomorrow.
