The Thai media outlet said custom-made gun components were also seized, as were suppressors (commonly known as silencers).
The Ministry of Foreign Affairs and Trade today said it was aware of a New Zealand citizen’s arrest in Thailand.
The Herald has also approached Royal Thai Police for comment.
Region 8 Police told the Phuket Express that Davies was arrested at a house in Soi Bae Hua in the Kathu district on Monday.
“Seized from him inside the house were seven rifles including an AK and M16, 19 handguns, 11 grenades, and many bullets,” the Express added.
“He was taken to the Kathu Police Station to face charges of illegal possession of firearms, grenades, and ammunition. His plea to the charges was not immediately made,” the Express added.
Immigration officers told the Phuket Express Davies had legally lived in Thailand for 23 years and his wife died five years ago.
Davies reportedly had work-related injuries causing disability and the media said he had no family or relatives in Thailand.
He previously worked on drilling barges offshore and retired at the age of 55, the Express added.
