Two men have been charged after a series of ram-raid burglaries in Hamilton and West Auckland.
In the last three months, offenders committed six ram-raid burglaries at commercial premises which sold high-end electrical equipment, police said.
A significant amount of stock was taken in each incident.
Police were particularly concerned about the most recent burglary in Hamilton on May 26 in which a security guard was allegedly threatened by an offender carrying a weapon.
Three search warrants were executed at properties in Hamilton, Huntly and West Auckland today. A significant amount of stolen items were recovered which were believed to be linked to the burglaries.
Detective Sergeant William Loughrin said gangs and organised crime groups were linked to the offending and police had not ruled out further arrests.
"At the West Auckland address police also located a number of firearms, a significant cannabis cultivation and precursor substances used in the manufacture of methamphetamine."
The two men arrested will appear in the Hamilton District Court this afternoon charged with a range of offences.
