The shop staff went to the aid of the van’s driver, and tended to him until the emergency services arrived.
Builders were called in later in the afternoon to board up and secure the damaged portion of the shop frontage.
“We will likely be closed for some time because of the extensive damage,” the spokesman said.
“We also had some shop stock damaged.”
The driver, the sole occupant of the van, was taken to Gisborne Hospital for treatment for what were described by St John ambulance as “moderate” injuries.
Police have an inquiry under way.
