Ousted Te Whatu Ora boss Rob Campbell says one of the biggest issues facing health reforms is the high degree of distrust among staff, which is causing people to leave the sector.
Campbell was sacked from the health agency last month.
He told Morning Report that government health care reforms need the active support of staff to move forward and make substantial change.
Campbell says in designing and implementing the health reforms there needed to be better communication by government and Te Whatu Ora with existing staff and entities.
