The Central Coast Greens have criticised a new community consultation process now on offer as part of plans to amalgamate Gosford and Wyong Councils.

Residents are being invited to have their say on the merger proposal - now the decision has been made.

The Greens have rejected what they claim is a 'fake' consultation process, describing it as the State Government continuing to 'ram through' council amalgamations.

The councils had their amalgamation approved by the Government late last year and will receive $20-million towards the costs.

Both organisations initially opted to 'stand alone' but agreed to a voluntarily merge in November and form a super council.

The government has now appointed an Office of Local Government delegate John Rayner to assess the merger.

Mr Rayner, who is also the former general manager of Sutherland Shire Council, will conduct several public meetings on the issue.

Online submissions can be made until the end of February.

A report will then be prepared for the Local Government Minister and the NSW Boundaries Commission.

Some of the issues to be considered include the financial implications of a merger, elected representation, staff employment, services and facilities as well as ratepayer attitudes.

But Greens spokeswoman Kate Da Costa is not happy.

"As the Premier and Minister for Local Government have outlined their intention to announce new council boundaries in mid-2016, the current process of calling for community submissions is a farce," she said.

"The delegate will report to the Minister, who has no legal obligation to do anything other than 'consider' the Delegate's report.

"The Minister would not be so confident of making this announcement if there was any chance that the Commission would reject a proposal" she said.

The new council is expected to be formed by the middle of the year.

Mr Rayner will meet Gosford Mayor Lawrie McKinna, Wyong's Acting Mayor Lyn Webster and both CEOs on Friday to discuss the process.

Details about the public meetings are due to be finalised this week.
