Oranga Tamariki East Coast regional manager Julie Tangaere said staff were advised to only attend emergency visits when required on Wednesday amid safety concerns.
"Staff safety is of utmost importance to us. We work closely with police to assess every situation.
"Thursday we will continue to assess this situation and make sure that appropriate support is in place to keep our staff safe while meeting the needs of children and their families."
