A victim advocate believes there will be more disclosures during a review of Oranga Tamariki.

The department has revealed two staff members have been stood down as they're investigated for alleged sexual misconduct with young people in the past year.

Former Police Commissioner Mike Bush will conduct a review.

Victims' advocate Ruth Money told Kate Hawkesby there could've been a vetting issue.

She says if people haven't been convicted or had a notation on their file before, they'd look clean - which is a huge issue with the vetting process around the country.
