Two men have been arrested after police discovered a clandestine drug-making lab in Auckland.

The "active" lab was found after two search warrants were carried out at properties in Mt Roskill and Albany on Wednesday, followed by the arrest of two males, police say.

The men, aged 35 and 26, have been charged with several offences relating to manufacturing, possession and supply of methamphetamine, says Acting Detective Senior Sergeant Richard Sami.

The two men are due to appear in Auckland District Court on Wednesday.
