The Berejiklian government is refusing to explain how it will implement its remaining council merger policy, leaving at least one Sydney council assuming the government has quietly dropped plans for more forced mergers.

The prospect of the bungled council merger policy remaining unresolved for another year or more is unnerving government MPs, and leading to discussions about how to fix the issue prior to the 2019 state election.

The Minister for Local Government, Vaucluse MP Gabrielle Upton has, through media statements, repeatedly affirmed the government is "committed to the remaining mergers", which have been delayed due to legal action.

But the minister has refused to explain how this will occur, leaving councils shrouded in uncertainty as they prepare for elections in September.
