Seven people have been arrested during a drug bust in Taupo and Tokoroa.

Police have been working on Operation Duet for two months, and carried out 10 search warrants this week.

Drugs, cash, ammunition and stolen goods were found during the searches.

Three Taupo men appeared in court today charged with supplying methamphetamine and have been remanded in custody.

Two men and two women are due to appear in court later in the week on charges relating to methamphetamine and synthetic cannabis.

Detective Sergeant Graham Perks says they can't rule out further arrests.
