In 1995, Bunye was again reelected as Mayor of Muntinlupa for his last three-year term. During his 12-year stewardship, Muntinlupa metamorphosed from a fifth-class municipality into a highly urbanized city. Adopting proven corporate practices that he gained from working in the private sector, Bunye initiated the computeratization of Muntinlupa, streamlined operations and cut red tape, thus making Muntinlupa City the business-friendly community that it is today. During his watch, Muntinlupa was consistently ranked by the Department of Finance as number one in Metro Manila in terms of realty tax collection efficiency.
