Investigators have begun an urgent review of changes to the Family Court in Auckland following strong criticism from lawyers.
They say the transfer of files from six courts to two central hubs in February this year has caused errors and delays.
The Law Society describes the system as fundamentally flawed, following months of case files being sent to the wrong places, protection orders going unserved and hearings being delayed.
Courts Minister Chester Borrows says that on Wednesday seven specialist staff from outside Auckland began an audit led by a recently retired Family Court manager.
Mr Borrows says a so-called register of issues has also been set up to identify problems and an overall plan to fix the situation will be in place by Friday.
