Katikati Police Constable Bernie Inglis said the 84-year-old driver from Katikati had pulled into the disabled parking space and stopped and then mounted the footpath.
Ms Inglis said the pedestrian, from Kauri Point was clipped by the car and complained of a sore wrist.
A St John ambulance spokesman said the driver received lacerations to the top of his scalp and was taken to the Katikati Medical Centre for treatment.
A passenger in the car was not hurt.
A police investigation is underway into the cause of the crash. Ms Inglis said due to the circumstances of the crash the driver will be required to obtain a
medical clearance from his GP before he will be able to drive again.
It is not yet known if the man will be charged.
A car has driven through the front window of the Unichem Pharmacy on Katikati's Main Rd.
Stacey McNeil of Katikati Antiques and Interiors said a silver hatchback appeared to have crashed into the window of the gift shop part of the pharmacy about 11.30am.
Police and St John were at the scene.
"It's just got its nose sticking in the window," Ms McNeil said. "There seems to be glass everywhere. It's terrible."
She was dealing with a customer at the time of the crash but said it appeared the driver has gone forward instead of reversing out of a car park in front of the store.
Police northern communications Inspector David Laumatia said a pedestrian had been bumped in the crash but there were no serious injuries.
A reporter on the scene said it appeared that an elderly gentleman had made an error and gone into the shop front.
"A pedestrian was knocked over but did not need medical treatment", she said.
