When writing letters, Ms Stokes told staff to sign off with "your sincerely" if they knew the person's name and "yours faithfully" if they didn't.
And Ms Stokes' own style for closing an email?
"I will sign off now, before I fall off my high horse ... R."
The email has been circulated among local board members.
Whau Local Board chairman Derek Battersby said Ms Stokes was right to point out the need for concise and clear reports, but it was derogatory to typecast elected representatives as 13-year-olds.
Ms Stokes, the former Auckland City Council's arts, community and recreation policy group manager, finished her council job on Friday and did not respond to questions.
