Police hope to know more about how a man suffered a "violent death" in a Kaitaia supermarket carpark once a post-mortem examination is completed today.
Pak'n Save staff found the man's body in a car about 8.15am yesterday.
They called St John Ambulance, the medics then alerting police.
The supermarket, in North Rd just outside town, remained open while a scene examination was carried out.
Police patrol cars stopped shoppers' vehicles entering part of the carpark where the body was found.
