An arsonist wearing a cat mask is being sought by police after he lit a fire at New Brighton Mall in Christchurch on Sunday.
Police were called about 11.40pm following a report of a suspicious fire at a store.
Initial reports suggest a door was also smashed and numerous items were destroyed in the blaze.
A young male who was seen in the area at the time has been described as blond and of a slim build.
He was wearing camouflage pants, a long-sleeve black and grey jumper, black and white shoes, and a cat mask.
