"They can stay for up to 12 weeks. In that time they have to work with a social worker to come up with some permanent accommodation."
Mr Anderson said that after the tenants left the emergency accommodation, the Salvation Army then works with them for another 12 weeks.
"If people are in a position where they need emergency accommodation, they nearly always have other issues. Often it's physical or mental health.
"We are seeing a lot of people with dental issues, which then lead to other health problems. For many people, just going for a consultation [with a dentist] is more than they can afford."
He said it was particularly difficult for women to find emergency accommodation in Whanganui.
Mr Anderson said the Salvation Army took on the responsibility for the rental accommodation.
He said the rental market in Whanganui was making it difficult to find suitable houses.
"We've been turning up to open homes, and we've been lining up behind 30 other people. We're really hoping someone can help us out."
