Two armed men robbed the Z service station on Dublin Street on Friday night.
It was the latest in a run of dairy and service station raids that have plagued Whanganui.
Police were called about 8:05pm to the Z station near Dublin St bridge. They said two males reportedly entered the premises armed with weapons (not firearms) and stole cigarettes.
A police spokeswoman said the thieves then left the store.
Police are in the area speaking to a number of witnesses and making further inquiries.
