Police are searching for three men who robbed a Christchurch dairy on Thursday afternoon, striking the shop worker with a weapon in the process.
The trio stole cigarettes and cash from the shop, on the corner of Riccarton Rd and Wainui St, just after 4:30pm.
It is believed they then fled the scene in a small blue hatchback car.
Police have released CCTV footage of the scene showing on of the men wearing a sweatshirt with "Thrasher" on the front, and another wearing a grey sweatshirt with a large letter P on the front and white arm cuffs.
Anyone who recognises the men, or saw any suspicious activity around the dairy earlier on Thursday, is asked to call local police on (03) 363 7400.
Alternatively, people can anonymously contact Crimestoppers on 0800 555 111.
