The Government has abandoned the sale of 249 state houses to an iwi housing provider.
Housing New Zealand had planned to sell the properties in Horowhenua as a part of a joint deal with the local council, which would sell another 115 pensioner units to a non-government organisation.
However, Housing New Zealand Minister Bill English said consultation with iwi had raised "a number of complexities".
In particular, the two iwi involved in the deal had not yet settled their Treaty of Waitangi claims with the Crown.
"The Government's Social Housing Reform Programme has always been about improving the lives of our tenants, and in this case, a transfer was going to throw up too much uncertainty for many of those involved," English said.
