Police want to hear from anyone who may have seen the woman who robbed the Welcome Bay Foodmarket at knifepoint get into the getaway car and the person driving it.
Tauranga police were called to the store on Welcome Bay Rd at 6.30pm on September 26.
The robber, who was armed with a knife and wearing dark clothing, with her lower face disguised by a black mask and a hoodie, fled the store with some cash and cigarettes.
Store owner Kuldip Kumar earlier told the Bay of Plenty Times the robber twice threatened to stab him with the knife if he did not open the till.
Acting Detective Senior Sergeant Craig Rawlinson said police were continuing to investigate the aggravated robbery and needed the public's help
