Private Investigation firm Thompson and Clark broke no laws when it sent a contractor to meetings of earthquake insurance claimants and recorded them, police say.
The State Services Commissioner laid a complaint with police in December following an inquiry into the use of the private investigation firm by Government agencies.
The complaint centred around allegations that employees of Thompson and Clark
Investigations Limited (TCIL) had attended and unlawfully recorded closed meetings
intended for Southern Response Earthquake Services claimants.
The Private Security Personnel Licensing Authority and Police investigated the complaint.
The authority investigation found TCIL did not breach the Private Security Personnel and Private Investigators Act 2010, nor was it guilty of misconduct, Police said in a statement.
Police had also found no criminal wrongdoing.
