A high-profile Auckland police officer cleared of a criminal sex complaint has resigned ahead of an employment investigation.
No charges were laid against Detective Inspector Mark Gutry following a complaint of sexual violation made by a prostitute last month.
The evidence from the nine-month inquiry was reviewed by the Crown Solicitor of Wellington before a decision was made this month to not pursue a criminal prosecution against Mr Gutry, who is married with children.
Mr Gutry, who has headed numerous high-profile investigations, was suspended from his senior role in the Counties Manukau police district in December while detectives from Wellington handled the case.
Despite there being insufficient evidence to lay criminal charges, the 48-year-old faced an internal disciplinary inquiry which centred on why he looked at the woman's file on the police computer system, known as the National Intelligence Application (NIA), up to 20 times over two years.
