Jami-Lee Ross has been sectioned to an Auckland mental health facility

This follows a tumultuous week in which Mr Ross traded insults and allegations with the National Party and came clean to his wife about his extra-marital affairs.

Mr Ross was taken in by police, and a source close to Mr Ross told the Herald that Mr Ross was "not in good shape" and "had been sectioned ... people who go willingly aren't sectioned".

Under the Mental Health Act, a person can be sectioned to a safe place against their will and given treatment if their safety is considered at risk.
