Four people have been arrested after police found an alleged methamphetamine lab on a rural property in the Coromandel on Sunday.
A man and the woman were initially found on an unoccupied rural property by two police officers travelling on 309 Road, south west of Whitianga.
The officers saw the woman sitting astride a quad-bike and a man in a utility behind her.
"The pair claimed to be at the property checking security but then the male, who had gotten out of his vehicle to speak to officers, ran back to the utility and was seen throwing an object out the window," said Detective Sergeant Dave Grace of the Waikato CIB.
After a search, the police officers found a jar containing methamphetamine, a .22 pistol, scales, close to $5000 in cash and a meth pipe.
Police later searched the entire property where they found two men inside a house allegedly operating a clandestine methamphetamine lab.
All four were arrested and charged with manufacturing methamphetamine. They will appear in Hamilton District Court tomorrow.
