"I've just left the shop. They are very, very scared," he said.
Police were combing through the neighbourhood to track down the men. A reporter saw several police cars at an address on Cheyne Rd.
Officers have also been seen stopping cars and asking drivers to identify photos of men.
Police at the scene initially refused to comment, saying a media release would be issued at a later point.
The robbery is the latest in a string of attacks on dairies and liquor store outlets in Tauranga.
On Wednesday night a man wielding a hammer tried to rob the Quality Food and Spices store on Cameron Rd. The attack came just 24 hours after a female staff member at a United Video was left traumatised after two men, one armed with a machete, held up the store and fled with a small amount of cash.
The Lucky 7 Superette on Maungatapu Rd was also robbed on April 26.
