The Herald understands a distinctive World War Two-era rifle used in many of the robberies, and which featured in public appeals to catch the robbers, has not been recovered.
Police believed a gang of heavily armed people were behind seven aggravated robberies in South Auckland in June and July. In each case the thieves were heavily disguised and used a variety of weapons, including the Lee Enfield rifle, a black pistol, a knife and a small axe.
No-one was hurt during the robberies but police were concerned someone could be injured, or even killed, if they didn't stop. It's believed the robbers got away with thousands of dollars.
A public appeal for information was launched after the last robbery in East Tamaki on July 14. It isn't known whether a tip-off led to yesterday's raids, which occurred in the same part of the city as the robberies.
One victim, Ramona Loto, 46, thought she was going to die when a gunman confronted her at Otahuhu's Gracie's Place on June 27. She pleaded with him not to hurt her as he prodded her with the rifle.
"I did say to him, 'don't hurt anyone. I've got kids and I want to see my babies'. He just picked me up by my jumper and said: 'Open everything and give us the money'.''
Ms Loto returned to work after the robbery because she didn't want to let the incident get the better of her. She wanted the culprits caught before anyone was hurt.
"They might use that rifle that's what I'm afraid of.''
