A survey has found that one in every 20 public servants has seen a colleague inappropriately accessing or misusing a client's personal information in the past year.
The finding doesn't surprise Accident Compensation Corporation client Bronwyn Pullar, who was sent files about almost 7000 other ACC clients in one of New Zealand's worst privacy breaches in 2012.
"I don't think New Zealanders appreciate the extent to which there is inappropriate and unauthorised use of information," she said. "It does raise serious concerns about the degree of access Government employees have over people's private information, particularly sensitive health information."
The survey found that the highest proportion of public servants who saw improper access or misuse of personal files -- 7 per cent -- was in the district health boards (DHBs).
The numbers were 4 per cent in core government departments, 3 per cent in non-DHB Crown agencies such as ACC, and 2 per cent in other Crown entities such as TVNZ.
