"Partly there is nothing in private rentals and they are at the bottom of the list. A lot don't have references and some have bad credit."
The trust already operates two properties in Whangarei: a seven-unit complex for families with children, and a four-bedroom house that could accommodate up to six men.
Mr Whale said about a third of the families inquiring about emergency housing had come from Auckland. He said a growing trend was the number of working families coming in.
"We're seeing a lot of families where at least one in the family is working but rent prices in Whangarei are so high and, when you have low wages like you do up here, families can't afford it," he said.
Because of the high demand the trust had to turn some families away.
"It's heartbreaking because it means we're the last resort. We certainly know of people sleeping in tents or caravans or cars as well," he said.
