The High Commissioner for India Ravi Thapar is leaving New Zealand apparently because of a police investigation into allegations of assault on a member of his staff.
Police will not say who the staff member laid the complaint against, but say the man returned to India three weeks after the alleged assault in early May.
They said he did not want to press charges, and when they tried to interview High Commission staff they were rebuffed and unable to take their investigation further.
They had since made welfare checks with the man, who said he was fine and happy to be home.
The Ministry of Foreign Affairs and Trade says it is aware Mr Thapar is preparing to leave New Zealand.
