The plan asks Kaipara people if they support the sale of non-strategic surplus property to free up funds to repay debt.
MRRA chairman Bruce Rogan said the protest was over the un-elected commissioners selling off Kaipara assets without any consultation and without waiting for the High Court decision on its review of the controversial Mangawhai EcoCare wastewater treatment scheme.
Mr Rogan said the council had bought the land in Alamar Cres with funds from the Mangawhai Endowment Lands Account holding proceeds from the sale or lease of former Mangawhai or Northland harbour board assets and local people were "up in arms" about the proposed "surplus" land sales.
"We are all objecting to the commissioners asset-stripping this district."
Mr Rogan said the "very satisfactory" turnout for the protest march was followed by the commissioners, led by chairman John Robertson, having a good exchange with draft plan submitters.
Mr Robertson agreed the hearing had been "good natured and constructive".
Commissioners were working their way through the 380 properties the council owned and finding out what people had to say about selling those which were not needed.
The protest was not only about land issues, Mr Robertson said. It was also about history and a desire to see justice done.
"The High Court is taking its course. We are not interfering with that in any way," he said.
