On Wednesday, Labor MLC Mick Veitch successfully moved a motion again seeking reports created by the independent Local Government Boundaries Commission as well as the government's legal advice to block their release last month.

Mr Veitch told NSW Parliament;s upper house that the reports held information that was "critical to the community".

"There are people who want to consider whether or not they will contest the next local government elections and they need to know whether those local government elections will take place and, if so, what entity they would be running for - whatever that may look like.," he said.

"They are concerned about what this will mean for the ongoing administration and governance of their local government areas in the future."

The Save Tumbarumba Shire and Gundagai Council in Exile have campaigned against the 2016 council amalgamations and have continued to protest ever since.

The groups claim that the NSW government's decision left residents with less input on council decisions and facing large rate rises or service cutbacks due to deteriorating budgets.

Cootamundra-Gundagai councillors voted late last month to explore potential legal action against the government over alleged financial damages resulting from its amalgamation.

Save Tumbarumba Shire spokesman Dr Neil Hamilton said the efforts to obtain the reports were definitely not over.

"The issue now is when the government will be forced by one means or another to deliver the reports," he said.

"The order to produce the documents stands; eventually they will be forced to release them.

"The Labor party will continue to push for this, as will the Greens, and the Local Government Minister {Shelley Hancock] has said they will be released. The question is when."

In Parliament, Finance and Small Business Minister Damien Tudehope defended the decision not to release the reports last month.

"The government understands the importance of taking time to carefully consider and examine the report prior to making a decision. It is essential for the communities of Snowy Valleys Council and Cootamundra- Gundagai Regional Council that these reports be carefully considered," he said.

"The minister has committed to making these reports public in due course. I am advised that these reports are currently Cabinet in confidence.

"The government asks for the consideration of the House in supporting a due process before supplying these reports. To that end it asks for additional patience from members before these reports are provided."

Greens MLC David Shoebridge told Parliament his party would support the motion.

"I hope that it does not get to the point of having to summons the boundary commission members to explain noncompliance," he said.

Gundagai Council in Exile spokesman Dr Paul Mara said it was "unconscionable" for the government not to have provided the Cootamundra-Gundagai report by now.

"We want the report released but regardless of what the report states, the only acceptable outcome for Gundagai community would be a demerger and the Local Government Minister must make that decision as soon as possible," he said.

Labor back in March voiced support for the campaign by demerger groups in both councils to release reports,

Last month the Department of Premier and Cabinet responded to motion demanding the reports by stating the Boundaries Commission, as an independent body, was not subject to the upper house demand.

"I know that members in this Chamber have been receiving correspondence-in some cases large amounts of correspondence-from residents in both of those council areas who want to see these documents," Mr Veitch told Parliament this week

"They want to see what the boundaries commission has recommended or put in the report to the Minister after going through the exercise."

Dr Hamilton said the volume of correspondence being sent to upper house members clearly demonstrated there was community support for releasing the reports.

"We don't understand why they won't release to documents; it's simply absurd," he said.

Nationals Cootamundra MP Steph Cooke, whose electorate includes part of Cootamundra-Gundagai Regional Council, has also called for one of the reports to be made public.
