A former Auckland policeman has been charged with 21 counts of accessing a computer system for a dishonest purpose.
The 34-year-old man, who no longer works for the police, was subject to a long investigation into his activities while in uniform.
He accessed the police National Intelligence Application system and dishonestly obtained personal information about 21 different women, court documents allege.
The names of the women have been suppressed. The accused also has name suppression.
The alleged offending happened over several years between 2010 and 2016 and in various parts of New Zealand including Wellington, according to the charge sheets.
Inspector Jill Rogers says police do not believe anyone else was involved in the officer's activities and say his actions are disappointing.
"We can however say that the integrity, professionalism and conduct of our staff is a key priority for NZ Police," Ms Rogers said.
The man was granted bail and will reappear in the Auckland District court on February 15.
