On July 27, Accessible Properties called to offer her an interim placement in a four-bedroom Mount Maunganui home until a larger property became available.
Miss Buchanan and her children will be moving into her new temporary home on August 4.
"It looks quite new, it is a nice house in a nice area," she said.
She has nine children who will be living in the home with her.
"They will be stoked, especially because it is in the Mount by Bayfair and the beach," she said. "We know we still have to look for another house but this feels awesome to know we are going to have our own space."
The family does not have any furniture apart from a washing machine and a few bedding items. But Miss Buchanan was just happy to have a roof over their heads.
"We will worry about that later," she said. "As long as we have got a house."
Miss Buchanan planned to find work and study now that she did not have to stress about finding a temporary rental.
"I am thinking of studying childcare or elderly care, something to help others."
Accessible Properties chief executive Greg Orchard said Miss Buchanan was not a tenant of Accessible Properties.
Mr Orchard said Miss Buchanan was told to move out of the state home because it was tenanted to someone else and the home was severely overcrowded.
"We became aware of the situation as part of a recent routine inspection and have taken steps to resolve the overcrowding including looking for suitable housing options for Miss Buchanan."
Mr Orchard said its contract with the Ministry of Social Development states it could only house people if they are referred by the ministry from the social housing register.
He said Accessible Properties was attempting to find the right home for the family and was working with the ministry on a long-term solution.
Ministry of Social Development regional commissioner for Bay of Plenty Mike Bryant said Miss Buchanan had a high priority rating on the social housing register, reflecting the family's urgent housing need.
There were 156 people on the housing register for Tauranga, including 121 on priority A and 35 on priority B.
He said a special needs grant was now available to meet the cost of short-term emergency accommodation.
A total of 3108 people accessed this assistance nationally in the quarter ending June 30, with 190 of those living in the Bay.
Mr Bryant said 68 transitional housing places in Tauranga and Papamoa would be available by the end of 2017.
"With those in place we will be able to support up to 272 families with an urgent housing need each year."
He said the ministry would be working to secure an additional 290 social housing places in the Bay, including 155 one-bedroom, 85 two-bedroom, 45 three-bedroom and five larger properties.
