A comprehensive policy on email quarantining landed on Horowhenua District Council's table on Wednesday and was voted in by nine councillors, despite the organisation still being under investigation for the practice by the Ombudsman and Privacy Commission.
The policy states that it is not acceptable for emails to "unduly interfere with staff and their decision-making processes, to criticise staff or to simply abuse and harass [them]".
Any messages thought to breach the policy will be categorised as either minor, major or extreme, and could land their sender on the council's quarantine list.
The policy follows local outrage and national debate on the issue after it was discovered through an internal audit that Horowhenua District Council chief executive David Clapperton had been personally screening emails, including some sent to elected members, who are not employed by him.
The audit documents, which were leaked to media, said the practice was an extreme risk, but the report was rejected by HDC, which commissioned accounting firm KPMG to carry out a peer review.
