"The reforms will be about improved cost control in the local government sector and will set out a work programme with local government," Dr Smith said.
Changes flagged by Dr Smith in the past few months include focusing councils on essential services, such as roads, waste, libraries, dog control and issuing consents.
They also focused on providing tools to control costs, such as the local government wage bill and chief executive salaries.
The minister has expressed concern about councils getting involved in social issues and taking on risky events, such as the V8 car race that cost Hamilton ratepayers more than $40 million.
The reforms could spell the end of regional councils, open the door to more mergers along the lines of the Auckland Super City and streamline the endless planning documents and bureaucracy imposed on councils.
The country's mayors and council chief executives have been invited to a series of briefings from Tuesday to Friday next week. Local Government New Zealand president Lawrence Yule, who has been briefed by Dr Smith on the reform package, said he was unable to comment.
