Two men have been arrested following a police investigation into the sale and supply of methamphetamine across Marlborough and Canterbury.

Organised Crime detectives executed search warrants at properties in Riverlands near Blenheim and in the Christchurch suburb of Belfast.

Detective Sergeant Dean Schroder from the Tasman Organised Crime Unit said officers from both Marlborough and Canterbury police districts were involved in the operation.

“We had the Armed Offenders Squad supporting us in the execution of the search warrants, with staff coming in from both Marlborough and Canterbury Police districts,” Schroder said.

During the searches, police located packaged methamphetamine, cash and utensils used for consuming the Class A drug.

Two men aged 34 and 57 have been jointly charged with conspiracy to supply and supplying methamphetamine.

The 34 year old was already on bail for methamphetamine charges and now faces additional charges including possession of methamphetamine for supply, possession of an offensive weapon, possession of cannabis and possession of equipment for consuming methamphetamine and cannabis.

The 57 year old was due to appear in the Christchurch District Court today, while the 34 year old remained in police custody and will appear in the Blenheim District Court tomorrow.

Detective Sergeant Schroder said “The investigation was a success and we’re pleased with the dedication and commitment of the staff involved in Marlborough and Canterbury for holding the men to account,” he said.

“We’ll continue to investigate drug supply and distribution in the South Island and will work to track down other offenders.”

Police are not ruling out further charges and said enquiries remain ongoing.

Detective Sergeant Schroder urged anyone with information about drug manufacturing or distribution in the region to contact police.

“Call 111 if it’s happening now, or 105 if it’s after the fact. You can also provide information anonymously through Crime Stoppers on 0800 555 111,” he said.
