Police have confirmed that a clandestine meth lab was found at the scene of an explosion and fire in Katikati last weekend.
More than a dozen firefighters from Katikati Volunteer Fire Brigade, Greerton and Mount Maunganui fought for five hours to bring the blaze, which erupted at a Katikati address on Sunday, under control.
Police said an investigation into the fire had been completed and confirmed a clandestine lab was found at the address.
The fire was allegedly lit by occupants of the property as police were executing a search warrant there, police said.
A 35-year-old man from Katikati, a 37-year-old man from Mateku and a 26-year-old woman from Tauranga have all been jointly charged with arson and conspiring to manufacture methamphetamine.
The trio appeared in the Tauranga District Court on Monday and have been remanded in custody.
