A rodent problem in the Far North has compounded concerns for poorer families amid the cold snap, as some children are having to sleep on flimsy mattresses on floors instead of beds.
In Kaitaia demand for Salvation Army services, including bedding for children, has been "incredibly high" so far this winter, said Lieutenant Nikki Mellsop.
"Lots of children are sleeping on the floor on mattresses.
"There is a desperate cry for mattresses and bedding," she said.
With the cold weather causing mice to make their way indoors, she said families were becoming increasingly concerned for children sleeping on cheap mattresses close to the floor.
