"The commission is listening to the views of a wide range of groups and individuals," its chief executive Donald Riezebos said.
The commission had held almost 200 meetings in Northland, Hawke's Bay and Wellington, the three regions where amalgamation proposals were under consideration, Mr Riezebos said.
"There have been public meetings open to all-comers and further meetings held individually with affected groups. Those groups include councils, iwi, chambers of commerce, local businesses, sector groups, funding agencies and ratepayer associations."
The commission held eight public meetings in Hawke's Bay last year. Mr Riezebos said those meetings were not required by legislation "but the LGC chose to travel to each region to hear first-hand from local communities".
Mr Little has previously complained that commission meetings in Wairoa last year were held at short notice and with little advertising.
Mr Butler and Mr Dalton have complained that the commission is promoting a pro-amalgamation agenda being pushed by central government, but Mr Riezebos rejected that suggestion.
"The commission must be satisfied there is community support for any proposal. As an example, last month the commission declined an application for Nelson and Tasman councils to be formed into one local authority, due in part to a lack of information about public support for change."
Once the commission has held hearings in Hawke's Bay it must decide if its amalgamation proposal has the required level of support and if it does it will release a "final proposal" which may include changes from the draft released last year.
The public will then have the opportunity to call for a referendum on the issue. That is likely to be held late this year or early in 2015.
