"We do want the result of not having our homes sold to private investors."
Ms Kururangi said the group was going to do more fundraising as the court case would not be cheap.
She did not expect a large contingent of people to be at court on the date due to the cost of travel, but said State Housing Action groups based near the Wellington area might come along.
"It will be good to get some serious answers and have our concerns addressed officially. I'm excited, and nervous as well. I'm feeling like we have all the information we need, anything else will be a bonus."
A spokesperson for the Government's Social Housing Reform Programme said the Government was continuing to work with the preferred provider, Accessible Properties NZ Ltd, to complete negotiations while the court process was under way.
"However, we will not be transferring the tenancies and properties to Accessible Properties New Zealand before the hearing," the spokesperson said.
"Whatever the court decides we will work to ensure the best possible outcome for Tauranga tenants."
Accessible Properties New Zealand was expected to become the new landlord around April next year, the spokesperson said.
Under a new landlord, state housing tenants would continue to be housed for as long as they were eligible for social housing. Their rent would not change as a result of having a new landlord, nor would their rights.
All the properties transferred would have to remain in use as social housing and could not be sold unless the Government agreed otherwise, the spokesperson said.
The Government would only give that approval if the house was no longer needed for social housing, or it was to be redeveloped to better match the Tauranga's current and future social housing needs.
