Two masked robbers, possibly with concealed weapons, forced a Masterton petrol station attendant to empty the till before fleeing on foot.
Wairarapa police have posted CCTV footage of two people who held up Solway Caltex on High St in Masterton on Friday night.
Police said the robbers, wearing dark clothing and with their faces covered, had entered the service station about 8.50pm.
They demanded money from the attendant, who was the only person working at the time.
One of the robbers had his hand in his pocket as if holding something, leading the attendant to believe he was carrying a concealed weapon.
