Five young people at an Oranga Tamariki youth justice facility in Christchurch climbed onto the roof last night, with one staff member receiving minor injuries during the incident.

The group went onto the roof at Rolleston's Te Puna Wai ō Tuhinapo just after 8.30pm, OT deputy chief executive of service delivery Rachel Leota said.

"All five were able to be brought down from the roof with assistance by members of the NZ Police just before midnight.

"Oranga Tamariki will be conducting a review into this matter."

One of the group has been taken into police custody, Leota added.

A police spokesperson said the youth has been charged with common assault.

"Charges are still being considered in regards to the remaining four."
