Corin, who had more than 45 years of experience, died while at the Royce Watson Memorial Hanmer Rally which ran across several forestry roads around Hanmer Springs.
MotorSport New Zealand president Wayne Christie confirmed the death of a photographer on Saturday night.
"The photographer was struck by a car competing in the rally, the car having travelled a considerable distance off the rally route," he said.
The competitors in the car were uninjured and the police's Serious Crash Unit was investigating.
"Our thoughts are with the photographer's family and friends, all those involved in the Hanmer Rally and our motorsport community as a whole who are understandably affected by this tragedy.
