Acting Waitemata East Area Commander Inspector Kevin McNaughton said that in March two men were arrested and charged for the aggravated robbery of the Mad Dogs and Englishmen Pub as well as a further premises in Papatoetoe.
In June, a further two offenders were arrested and charged for three aggravated robberies, one being Vino's Bar and a further two premises in Auckland City and Waitakere, he said.
Police have bolstered their presence on the North Shore after the brazen aggravated robbery of the Good Home, which is still under investigation.
The two masked robbers, one carrying a gun, entered the bar shortly after the Bledisloe winning All Black match had ended.
A witness previously told the Herald they were threatening and one of the offenders struck a patron over the head with the butt of the gun before firing a warning shot.
McNaughton said the aggravated robbery on January 9 at the same premises "is an active and ongoing investigation".
"We do not have any information at this early stage to suggest these matters are linked to Saturday night's incident however we are keeping an open mind as our investigation progresses," McNaughton said.
"We urge any members of our community who can assist us in identifying those involved in these violent crimes to contact Police."
Police recently appealed to the public to come forward if they had seen the stolen white Subaru in the area on the night of the crime.
