On Friday four people were arrested in connection with the aggravated robbery of a driver in North Dunedin that morning.
The Otago Daily Times contacted five Dunedin taxi companies but all said they were not aware of who employed the driver.
Dunedin Taxis manager Simone Green said these kinds of attacks were not common in Dunedin.
"Fewer attacks happened since cameras have been installed.
"The cameras have acted as an active deterrent against this sort of behaviour and helped to minimise risk to drivers."
Hers was not the company whose driver was attacked.
Cameras were there not only for drivers, but for passengers too, she said.
"Safety is a two-sided process.
"These sort of attacks are not pleasant, whether you are a taxi driver or a dairy owner. As the Dunedin public, we don’t like this happening anywhere."
It was all the more reason to use reputable taxi companies, she said.
A police spokeswoman said a 33-year-old female and a 21-year-old male were arrested for aggravated robbery in relation to the incident.
A 27-year-old male and 20-year-old female were charged with receiving property.
All four are to appear in court on January 12.
Senior Sergeant Jared Kirk said police were called to the scene in Norwood St, Normanby, about 3.30am.
After arriving, police established four offenders had threatened the driver before running from the vehicle.
Police dog units responded and tracked the suspects.
Four people were located a short time later and were being spoken to by police.
The taxi driver was not injured but was "understandably shaken", Snr Sgt Kirk said.
Police were providing support.
