Professor Bashir wrote to Mr Kelly in November after receiving a letter signed by 11 prominent Lake Macquarie and Central Coast residents who complained to her about the government's handling of the project's assessment.

She asked Mr Kelly to respond directly to the residents' concerns and also send a copy of his response to her office.

Neither the residents nor the Governor's office had received any correspondence as of Friday afternoon.

"We certainly haven't received anything yet. We are still waiting," a spokesman for Professor Bashir said.

Residents who signed the letter included Lake Macquarie Mayor Greg Piper, author Peter Yeldham OAM, Member for Terrigal Chris Hartcher and Wyong citizen of the year Garry Prince.

"The state government has over a number of years demonstrated, through its representatives and agencies, an unwillingness to be transparent, a refusal to be accountable, and on occasion by its action humiliated the constituency of the region by untoward political action," the letter said.

A spokesman for Mr Kelly said the minister's response would arrive in the near future.

"This matter remains under consideration following the Planning and Assessment Commission which held additional public hearings late last year," he said.

"Because this is such an emotional issue in the community the minister wants to respond in detail."
