An investigation into a top police officer who allegedly forgot files in a cupboard has been widened to include seven years of his work at Auckland Central police station.
The officer at the centre of the investigation is Detective Senior Sergeant Mark McHattie, the head of the CIB's serious crimes squad.
McHattie was stood down in January but is back at work on restricted duties.
A source confirmed that the internal investigation into how the files were forgotten has been broadened.
It is understood the investigation initially only looked into the forgotten files, but it will now include all the files he has managed in the past seven years.
