The movable homes will be sold for their residual book value of $24,510, which Smith said was a significant discount on their market value.
The farmers will also have to cover the cost of relocation, connection of services and will need to obtain consents from their council.
Thirteen of the 20 Rawhiti units are available, and more will free up as tenants' home repairs are completed.
Smith said 18 farmers in the Hurunui district, five in Kaikoura and 5 in Marlborough could benefit from the accommodation, "although the economic viability of relocating the homes to Marlborough through the Lewis Pass may not be viable".
