A family accused of abusing foster children in their care by using a wire brush to scrub their bodies will go on trial later this year.

Andrew John Hemara, 53, and Jenny-Lee Hemara, 49 appeared at the Auckland District Court today where they were remanded on bail until their trial in August.

An 8 year old boy and 7 year old girl were abused for several years.

A teenage boy has been jailed for more than four years for sexually abusing two young children who had been placed in his family's care by NZ Child Youth and Family.

The youth's parents were also convicted of physically assaulting a child in their care.
